This made me chuckle. So it doesn't matter if fire could sleep/ignite as AA, leech like lightning, clear debuff/shield as mystery, deal way more damage to summons and reduce opponents' resistance?
Or how water can deal multiple chaos, cancels shields and buffs, heal for both AA and mystery, gives poison for all her side attacking?
How about earth generating crazy shields, can't be combo'ed, give everybody extra attack, wb asuma buff?
Or wind resets all cd while removes all debuffs, keep generating clones that could attack, can do giant rasengan mystery back to back like fire, leech hp if receives chakra?

All characters got their pros and cons. I don't see any point to whine about. lightning was nerfed when they changed root of warrior passive. If i recall correctly, last time it increases all swordie's attack by 40% instead of now 100% resistance.

...also knockdown/high float debuff? dude what?
