This is what I'm most excited about. Rumor has it that it will be more like Diablo style instead of a typical skill tree. I wonder if it's for additional skills on top of the already established ones, adding to those already existing, or both. It would be nice to specialize in certain skills which suit your play style and team position and also gain certain ones by choice.
It would also add a the dynamic where you have to watch people play and figure it out, perhaps while fighting, paying attention to certain things and adjusting accordingly. Would make combat more involved.
