Personally I think Kanna's kishin should be weaker than the fury totem (Example, kishin should be 30% respawn/mob boost and fury totem should be 60%). And Fury totem should be made to be way more accessible than it currently is. I don't think Kanna deserves a free permanent fury totem at their disposal while also having the best mobbing, and the best support while having really good bossing to boot. The problem with kanna is that it's the only class that has the best of every world. There is no cons to being a kanna whatsoever.
And yes this is coming from a kanna main. I also think they should seriously nerf our bossing and balance our mobbing more too because it's OP. Kanna doesn't deserve to be broken in all possible directions. Kanna is supposed to be a support like Bishop. Not a full out DPS class, full on support class "and" full on mobbing class with a permanent fury totem built in.
