Can someone explain to me what's so great about witches?

I don't play with witches. So for me, there's nothing special about them. Or other occult lifestages. But for those who do play with them, it adds depth to their playing style. And usually when we get an EP with them in it, objects, clothing and new recipes come along which gives those of us who can care less about witches, a reason to by the pack. So it's a win win in the end! :D
