Yes it is. Every opinion is helpful, it makes me think if it does nothing else. And yours was more than just that.
(Light and Shadow are mostly telepathy/empathy, illusions, hiding... potentially useful in spying or war, but the other side has them too. So, um, yes, it seems I definitely must include the blasters and earthshakers and freezers and blowers-away as well. I don't intend to make /most/ mages oh-so-powerful, but they could probably do quite some harm. They certainly /don't/ have Aes Sedai oaths :P)
