Has there been any talk about how dull casters like priest look when doing anything?

Be it staffs or offhands, when it comes to casting spells, they don’t have any bearing on the visuals.

I wish you could actually see your equipments being involved when I’m using mind blast or smite.

I’m sure I’m not the first guy to feel that way. So wanted to know if blizzard have recently talked about reevaluating how casters combat stances could be updated.
