I get what you mean but I have two reasons I disagree, first I think the animations for AoE abilities are cool, like freeze and I'd be sad to see a lame WoW system where every slash ends up cleaving all the enemies. As for single target replacement abilities like Xenoglossy and Senei are not only cool, but they allow the devs to have some filler abilities, by having these we slow down the change of a class and slow down the need for reworks (hopefully at least)
