C) Characters needing buffs:1.
Shino 
Make the Female Bug increase dmg by 10 from 5, matching Namikaze Minato.
2.
Zabuza 
Silent Homicide Technique - this skill is nearly useless without the mist. Change base dmg from 30 to 35.
3.
Tsunade 
Her Self Heal is too unreliable. Change cost to 1 nin + 2 random. It can only be used once per game, similar to Tobi's Izanagi. Leg kick could destroy target's destructible defence.
4.
Jirayia 
Toad Mouth Bind - this genjutsu is too weak and in most cases not worth using. Sometimes its literally better to wait for chakra swap instead of using this terrible skill. Using a little bit of math you see youd need to deal 140 dmg to opponents to make this skill worth 35 dmg. And thats only AFTER youve spend a turn and 2 chakras casting it. I suggest changing the cost to 1 genjutsu. If not then maybe change his fire to deal 10 aff dmg (from 5) to side targers.
5.
Shukaku Gaara 
This guy seems so cool, but its sad that currently, he's only being used as a setup for action skills, for example Sand Prision into Hinata's chakra removal. His Shukaku transformation is way too weak, which is a shame because its such an awesome character. Waiting 5 turns to unlock 60 dmg for 2 blood is not worth it. It should be a glorious moment for the player, getting the transformation off, but instead is very disappointing. I suggest changing:
- Shukaku transformation gives 1 chakra the turn after its used, or change the waiting time to 4 turns from 5.

-
True Awakening - this skill absolutely sucks. You pay a very important for Gaara blood chakra only to get a boost for 1 turn. After you use it, enemy just blocks becoming invul and you've just wasted a precious turn of your transformation (not to mention that enemies want to block during strong transformations anyway, like during Gai's 2 turn gate opening) as well as a very important blood chakra that could have been used to deal 60 dmg.
Change suggestions:
- chakra cost changed to 1 random from 1 blood - very important not to use precious bloodline chakra
- Gaara goes to sleep for the remainder of the transformation, letting Shukaku take over, instead of just 1 turn. Or maybe Awakening last for the entire transformation until Shukaku Gaara is damaged (getting through ddef or dealing affliction), with a minimum of 1 turn. This would be more faithful to the manga where it was hitting him that caused him to wake up.

-
Sand Claw during the transformation costs 1 random instead of 1 bloodline OR Sand claw costs 2 random chakras and deals 40 dmg instead OR keeps its cost and dmg but targets all enemies

-
Drilling Air Bullets - this skill is okay, but could be better if it cost 1 blood 1 random (from 2 blood) and dealt 50 dmg. Still keeping the OTK aspect with awakening, but at least Gaara could do more during his transformation, as lacking bloodline chakras is often a big issue for him OR change the cost to 1 blood 1 ninjutsu, which would make him less reliant on bloodlines only.
Now im not sayying ALL of these suggestions should be applied at the same time, but I recommend trying a couple of these. His biggest issue is always lacking bloodline chakras for doing cool things.
6.
Morino Ibiki
He currently has 1 good skill. Torture chamber is simply not worth casting (similar to Jirayia's toad mouth genjutsu), using 2 chakras to later deal 20dmg for one random. Its a mockery compared to Asuma S fists. I suggest increasing the dmg to 25 piercing and the "captured" enemy cant use stun skills.
7.
Kankuro S
Karasu Knives are simply not worth using without the counter proc. Delayed 30 dmg for 2 random with 1 cd is easily the weakest 2 random chakras skill in the game. This skill's damage should be increased from 20 to 25 or from 10 to 15aff. Would probably be fine even with no CD.
8.
Killer Bee
This character is too slow, paying 1 random and a turn to increase his dmg by 10. I suggest changing the stance's cost to nothing and if thats too much, then the dmg increase on buzz saw should only be 5. Why does making a stance cost chakra, but basic Sasuke's sharingan cost nothing?
9.
Uchiha Sasuke S 
His Fire Dragon skill is currently weaker than Kankuro's bomb, despite costing ninjutsu instead of random and having a 1 turn window to cast it. I suggest changing the dmg to 12, or making it affliction, or both. I think changing the cd to 2 turns or even 1 could be a good change for him and make him more useful.
10.
Kisame Body Double
Explosive Water Shockwave (skill #1) is too weak for its cost. It should either cost 1 blood only or grant some extra bonus, like dmg reduction for his team.
11.
Kakuzu 
Raiton Gian is too weak. Dealing piercing dmg is not equivalent to a stun, comparing to his other skill), not even close. Its damage should be increased from 30p to 35p.
Inferno Gust is too weak compared to its cost and 1 turn window of usability. I recommend increasing the dmg to side targets from 15 to 20.
12.
Uchiha Itachi
His counters/reflects are strong, but his amaterasu is lacking. I recommend changing the dmg from 5 to 7 OR maybe 1 turn after casting Mangekyou Sharingan, amaterasu immediately will target all enemies immediately, paying homage to how he used to be before rework. If those changes make him too strong then maybe his genjutsu could be nerfed to only counter 2 of 3 skill types instead of all types.
13.
Asura Path Pain
Nerfs made his op skills balanced, but his Heat Seeker is too weak and is often not worth casting, even when his getting focused. I suggest changing it to 25 piercing damage and have this skill ignore invulnerability.
14.
Preta Path Pain
Chakra Pin is rather weak and could use maybe dealing 10 dmg?
15.
Tobi 
While this character was possibly the most overpowered in the history of the game on his release (and even after his micronerf), now hes been buried into the ground. His issue was 2 turn, piercing, ignoring invul, deletion during his sharingan, so in other words the 100 % dmg increase. Now his sharingan is rather weak for its cost and short duration. I suggest one of these changes to bring him up a little:
a) Sharingan cost from 1 blood to 1 random
b) Sharingan Kamui boost 15 dmg from 10 dmg
c) Sharingan lasts 4 turns instead of 3
d) Kamui if used on already affected target increases its dmg to +10 instead of +5
16.
Shodaime Hokage 
His
Birth of Trees is too weak. It should either:
- last 3 turns, or
- grant his team damage reduction, or
- make his other skills stronger (+10 or +5 dmg or reduced costs)
17.
Nidaime Hokage 
He's too easy to stun and kill, making his aoe useless. I suggest making Water Collision Destruction granting him 50% dmg reduction, or maybe make the dmg reduction on enemies both melee and ranged.
D) Characters needing reworks (general or only on some skills):
1.
Orochimaru - why does Kusanagi remove chakras? Is there any mention of it in manga/anime? Major Summoning Manda is the same, it could do a lot of other interesting things. His game identity of chakra remover seems bizarre and idk where it came from. He's also underpowered, with Cursed Seal being the only nice skill. I recommend:
- change Kusanagi to 1 blood 1 random, dealing 35 piercing dmg
- Major Summoning Manda - Orochimaru summons Manda, wrecking the battlefield. The following 3 turns 3 random enemies will take 25 damage and have their physical and ranged skills stunned for 1 turn. During this time Orochimaru will ignore stun effects. (Similar to Juugo's killing rage, except stunning as well)

2.
Naruto S - while 2 of his skills are okay, Kyuubi Boost is a weak skill. You pay 2 chakras, 15 hp and a turn to get 2 chakras in return. Do you see how terrible this is? Such a skill simply has no right being good. Naruto S is almost always used as a chakra generator (for Gaara) rather than an actual character. If we want to keep boost this way, then a better choice would be making him immune to stuns or 1 turn and next turn Oodama Rasengan will be free. This way its still the same for him but he's not a dumb chakra generator. But to make it balanced the bonus still needs to be increased or the cost reduced.

3.
Preta Path Pain Rinnegan Absorbtion (#2 skill) - this skill is weird and doesnt work the way it does in the series. He should be protecting himself or an ally from chakra attacks, absorbing them. Thus, I suggest:
New Rinnegan Absorbtion - Preta Path Pain targets one ally and himself. For 1 turn all enemy chakra skills used on them will be countered. Preta Path Pain will gain 1 random chakra for each skill countered. This skill is invisible.
Type: Chakra, Instant, Unique
Cost: 1 ninjutsu
Cooldown: 1 turn

4.
Sennin Naruto - he's fine right now, but his skills are a bit weird and hes not as cool as he could be. He's often very strong with getting right chakras and situations or just he doesnt do much except Frog Kata Kicking people every second turn.
Rasen Shuriken is hard to pull off, costing 2 specific chakras with a tiny window of 1 turn to cast it. Deva Path Pain at least has 2 turns to cast his big replaced skills.
Sennin Naruto's Sage Revitalization skill doesnt make sense. In the series he uses it to get sage chakras for sage skills. Now it heals him for some reason. I think it would be more sensible to have that skill do less and prepare the Rasen Shuriken.

-
New Sage Revitalization - Sennin Naruto replenishes his sage chakras. For the next 2 turns Sennin Naruto will ignore chakra removal/stealing effects and Frog Kata kick is improved and will deal +10 dmg. This skill becomes Rasen Shuriken for 2 turns.
Cost: None
Type: Chakra, Instant, Unique
-
Rasen Shuriken - the same as the current one, except it can be countered or reflected (its LITERALLY countered by both Preta and Deva in the series XD )
-
Frog Kata Kick - same as the current one, cd 1, doesnt become rasen shuriken after usage.
- Personally I would also remove Natural Energy Assault and just leave him with Rasengan Barrage with cd of 1 or 2
E) Weird cases:
1.
Shikamaru's choking should be of type action (why is the skill performed even after his death??? XD ). To make him stronger he could gain 25% dmg reduction for 1 turn after meditate, or against that specific opponent he meditated about.

2.
Animal Path Pain's Cerberus Hydra should be ranged instead of melee. Or is Animal Path Pain biting enemies' butts as well? XDD
I know this is quite a lot, but all this has been on my mind for a long time, after discussing it with some players.
