Playing as a mage, in tough Rift fight, want to back away while continuing to blast away with my staff - no way!
Have to stop casting, and then it seems to take a second or even two before he starts moving; and then he moves like an arthritic old lady who has lost her cane.
Not sure if it is a design choice,or just plain control lag (ala Witcher2)
I feel the pain, but it kind of makes sense... in a twisted, ignorethefactthatiftheywererealmageswouldtotallybeabletodoit kind of way. Magic requires concentration, and apparently, knocking heaps of arrows in vaguely the same direction doesn't.
Although, I think it should be that mages can fire their regular attacks and move at the same time, since they're using their staff to deal damage, rather than their hands (or whatever else is possible). While casting a spell should not allow for walking. It would make sense that archers can use abilities and walk at the same time (I don't remember if it's possible, since I've not played an archer), since it shouldn't require a significant amount more of concentration, due to - usually - being the same movement/animation.
Anyway, my guess it's a design choice.
