Sacred Haven of Debauchery

Hey everyone, has anyone played Heroes of Might and Magic II with the expansion? What's the difference between a regular cleric and the new one that doesn't choose domains?
I want to start a new game and I'm trying to decide which hero to choose.
P.S. You can also tell me about the Shaman.
P.P.S. I have a pirated version, and the translation isn't very good, so if anyone knows where I can download a good translation (with a good font), I'd be doubly grateful.
