I saw somewhere (not exactly sure, and too lazy to look it up) a spoiled controller setup, and how the characters access each of their abilities. from what i saw, they each have up to 3 unique abilities available at any given time. There's a movement ability (ie: warlock's hover-ability), a lesser ability (warlock's solar flare) and the super (warlock's nova bomb). So some space magic is still not classified as a super, but the "coolest" stuff is, for the most part.
i haven't either, i just figure they're going to do something like that for all the classes, otherwise it would just be a jerk move to the other classes in terms of customization.
