it exists, is called 'resistance'. jokes apart, i think too there's an issue with ignition. I consider poison fine as is now for how hard is to stack it 4 times and keep it a 4 times.

the main problem with ignition is not much the damage itself that lands, but the way it denies healings. Imho ignition, unless the difference between the attacking ninjutsu and the enemy resistance is huge, should deny only a part of healings depending on the ratio between them.

So lets see if i understood correctly.

You want a full damage dealing team wholly unbalanced towards the damaging side with 0 passives about debuff cleaning that has no side effects even if is not full immune to debuffs.

Balanced, indeed.

That said...

The max damage possible if you get poisoned 4 times is 7996 per round.

So, not even in 4 rounds you are going to endure 32k damage from poison, and beware that multiple poison chases attach it only once (so, for example, if you use utakata, kabuto snake cloak, king of hell, and you hit the 30 combos, your whole 30 combo streak, composed of 3/4 poisoning effects, attached ONLY 1 STACK OF POISON per target).

The only way to attach it more than once per round is by using different standard attacks/mysteries and it's enough 1 single debuff removing effect/healing to clear all the stacks in a row.

and who doesn't run heavy shielding teams have issues in enduring angel god konan or edo hiruzen teams

and who runs heavy buffed teams have issues in facing han + kisame samehada/roshi teams

and who runs heavy cc teams have issues facing evading ninjas.

the counters to heavy poison+ignition teams are full immune teams and/or heavy removing debuffs teams (for example teams based on nagato or kakuzu earth grudge or gakido).

P.S. Anyways guys, if you worry so much about poison, means you still never faced a real shark bomb team and no that team don't run poison tai and no, not only in the future won't be nerfed but will be buffed.
