i'm honestly think water main with chaos and shark bomb is an old school thingies,but the fact he steal remaining cakras does not buffed that much. as for fire main sealing mystery its still under buff, hit only 1 target. unlike other immunity wind main that give to 2 female or LM up to 3 ninjas? and don't forget those immunity are a passive ability while fire sealing is a mystery, so that's mean if fire main choose this mystery he can't give shields and immunity... so its still under buffed in my humble opinion.

but to be fair. i think how shark bomb and Neurotoxin is kinda a bit unfair same as like LM chidory. the problem with those are the game mechanic its self. i think its over buffed to effected unselected targets. while earth main,wind,fire only deal dmg to their AOE mystery. while water and lighting having those cc to unselected.

to be noted this is only from the main only perspective, apple to apple, main to main not the whole team compositions. and i think this is more reasonable than 3.0 or 4.0 that too favor on LM and WM.
