Diablo 4 animations

Hi, i am a vivid diablo player and a huge fan of the all franchise. Just wanted to suggest the idea of in diablo 4 in this case each class having to acquire through either playing the game for a certain hours or through patches maybe different animations for either casting spells, with melee classes different animations for hitting slashing pounding. The idea would be of either winning these animation through game progression or through completing certain hard quests. Instead of having the same animations for so long the game is played maybe it would be fun and refreshing having this sort of feature. I think there isn’t an RPG h&S that has this feat.
