Voodoo Powder instead of Mana?? I don't know about anyone else but i think it would make alot more since for the wizard to use mana then the witchdoctor. Or maybe no one uses mana and everyone has there own system? Like the barb uses fury, the witchdoctor uses voodoo powder, the wizard uses ???, the monk uses ???. Voodoo Powder fits in with the witchdoctor theme and it just makes more since. I don't know how the witchdoctor would use his voodoo powder but i think the name Voodoo Powder is alot cooler than mana for the WD. Do you?
