weird thing about casting

[TypeZ]

sometimes i click on the spell and there is the sound that confirms the spell is being selected but nothing happens,no message that the spell is casting! or cancelled.

there is much more stress when healing with this problem,sometimes i button mash the spell and the casting get cancelled lol

does this happen to you mages?

That's not weird... The weird thing is the one hand casting that make job casting class look like a joke. the awkwardness of casting with no motion. You only see a hand flash and spell is cast
