Show talent area effect

[qui]

Right now there is no way to see what will be the area of effect of a talent that's centered on a character - in particular I have Stone Warden's Eldritch Slam in mind. It has large AoE, and quite often I have no idea if that orc will be hit or if it's just outside. I propose that the area be highlighted if I hover the mouse pointer over the talent. Alternatively, require two keypresses to activate - one to show area, second to fire. Personally, I'd prefer the former, as it's not all that often that I need to check, but that's just my experience with playing Stone Warden.
