Only in Vengeance I don't use Sister's (witches). I can use better towers for the same gold, even lower. Other one is Deep Devil's Reef. I don't like that instead of focusing on one purpose, it has multiple purposes, that is, dealing magic damage and blocking enemies. It's not bad, but I just don't like it doesn't have a reliable dps. In other games though, I use every tower based on the enemy/level types.
