objectively speaking, some adjustments need to be done.

On next patch poison cloud becomes with 2 rounds cd, Reserve Seal gets replaced by a 40% chance to dodge an attack twice per round and Shark bomb steals chakra too, like kisame's.

But i don't actually think this solve the issue of the missing availableness of a crossteam buff nor the fact that poison tai is too easy to be negated (by healing, debuff removal and also immunity).

About reserve seal i think it should have stayed, just with a higher boost to critical rate than that 1%. 3% would be actually fine.

he was saying that it should happen if and only if you select reserve seal as a passive and only for azure fang, not for the whole lineup. It's just another way to get healed regardless the ignition if and only if reserve seal is selected (beware that if you select reserve seal you can't select poison tai, clone or experimental ninjutsu, that makes really hard to actually play azure fang as a full healer).

Just try to think about the fact that the whole point of reserve seal is to grant azure fang more survivability, but if the healing part is negated (and is really too easy for it to happen even without targeting her directly) then its very purpose gets wholly negated, so why should somebody select it if basically every current meta lineup is able to make that passive wholly useless?

In the meanwhile we have wind and lightning main that get two rounds of full immunity, earth main that gets a stacking defense passive and fire main that reflects 1 debuff per round and makes immune the lineup once every 3 rounds.

Beware that also his other proposal would actually be not out of mind because, depending on the situation, would be actually worse to get healed by a standard attack/mystery than by the actual effect of reserve seal (for example if you are shielded by an 11k shield from gakido and you get comboed 10 times, reserve seal heals 30% of azure fang hp, there's no standard attack/mystery that is able to do something like that) so his proposal is not out of mind if you want to keep the actual purpose of granting more survivability to azure fang when that passive is selected.

As i said, personally speaking, i would just make the passive stack 3% critical per hit endured instead of the actual 1%, considering that critical rate is actually also a defensive stat. That would be more than enough to make the passive appealing if you want to play on the shark bomb/taijutsu attack/neurotoxin style.
