I think realism of character animations is overrated.
I myself don't even notice those animations, I mean how can you notice them in end-game content, when in encounters there is so much stuff to do, like watching your cooldowns, procs, dots falling of enemies, your self buffs ending, avoiding aoes and other kind of abilities and reacting to all kind of stuff..

Animation realism of your character at that point doesn't really matter, as you rarely are watching your own character in encounter. Of course beautiful animations are nice to have, but they should never impact gameplay negatively, and they do now.
