With artifacts being implemented, wouldn't it be a good time to update animations for casters so they actually use their weapons to channel/fire spells from?
While melee characters get to swing Ashbringer around, Felo'melorn is essentially nothing more than a fashion accessory.
We also see Ret Paladins getting yet another new attack animation in the feature overview trailer. Hopefully the rest of the classes get to see some of that as well. I'd love to see the other melee classes getting some unique attack animations, and some more interesting casting animations for casters.
