I don't think there is any point talking about balance until the end of the week when we will have all new minions and avatar forms that will more than likely be game changers.
I expect the fastest way will be to order it from Wyrd during Gencon and take the hit on postage etc.
Gotta imagine it would be better the more you plan to buy if I was after just a book I think I would wait till its released over here.
