I'm not sure if there is a proper page to make this kind of thread, but here we go:
not having 3 copies of certain cards feels like an unnecessary handicap in the core set; and paying for a whole other box just to get a few cards is quite a waste of money (especially since you won't even have 3 copies of everything, thanks to the one-offs like unexpected courage)
IMO, it would be nice to have a separate pack which comes with the remaining copies of core set cards. if my counting is correct, it would be a total of 64 player cards, which could be sold for the value of $15 (the cost of a 60-cards AP)
