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

I have more fun doing things in the game that I can't in real life and don't enjoy family/legacy gameplay, so things like Witches are highly appealing to me. Also my birthday is on Halloween (plus it's my favorite holiday) and I associate it with witches, so I just need them to be a thing. My simself is becoming a witch first thing if/when we get this pack.

There's not anything specific I want to see in this pack though. Others have better ideas than I do and I'd like to be surprised.
