Sacred Haven of Debauchery

for example, mages are overpowered

Mages and Nosferatu. Well, he's not entirely wrong. In some mod, it seems, to balance warriors against mages, they gave them a second attack... which made the heroes in the mod even stronger than they were in the original game.

succubus and shadow are terribly unbalanced and something needs to be done about them

Well, I also agree that succubus could use a buff, considering that incubi are better in almost every way. Although I still play with succubi. But additional buffs for shadows are definitely unnecessary, lol.
