Kanna has the best mobbing imo (and many people say she has the best bossing too, but this I don't know).
Im ok with her mobbing skills, she is really amazing clearing maps.
The only problem is kishin, which imo should be removed and a "kishin" effect added to every map in the game so everyone has the same possibilities. I feel so dismotivated when training in my main knowing my kanna level up faster just because of kishin..
Anyway, this is my oppinion: Remove Kishin Shoukan, Add "Kishin" effect to every map to everyone be equal on mobs spawn, remove wild/frenzy totens (because they shouldn't stack with a kishin effect anyway).
The Frenzy Totem is such a blatant pay2win item. It's just as bad as kannas having Kishin Shoukan if not worse. Now that it's gone, it gives the people who do have it an even bigger advantage.
