I was told by Kuro that one of my more complex character concepts could possibly be accomplished via multiple styles of magic.  So I would tentatively say, "yes".

The magic is taken from World of Warcraft so I would further posit that anything you see In that game should be okay. 

The key, of course, is to try not to overshadow other players.  For example: Siv and Raze are both ranged fighters.  Raze can deal more damage but can't hope to match Siv's range or her accuracy.
