I'm pretty sure that you need it for projectile spells... Anyway, mine is pretty much broken when it comes to switching targets. I have to flick the stick around for about three seconds before it switches targets and even then it only works half the time.

Anyone know if this was caused by a patch of if it was like this at release? I don't see how this problem could have been overlooked. It's not breaking the game for me or anything, though; I'm still having fun!
