This has probably been asked before, but I can't find it, so if this is a double I'm sorry.
When we play JitD along with AoD, we always complain that the overlord is overpowered, and it is really hard for the heros to win. Dark relics, Gluttony, Dark Glyphs...it all seems unfair for the heros. I've heard that ToI fixes a lot of balance issues and it is the expansion I'm getting next. Until then, however, are there any house rules to balance the game out?
