I'd especially like a way to get twice as many damage, mana, and ready tokens without buying a second core set. I very rarely need more than 9 dice for attacks and when i do, its not a big deal to re-roll blanks for the remainder. Not a problem either for 2 players to share, imo. But for games with more than 2 players, i def see limitations - but 2nd core set is the way to go there i think anyways.
Slightly off subject, but why keep printing Initiative tokens??? At least print one side black & white/darker so players dont have to pass back & forth, just flip over (if theyre going to keep on showing up in expansions).
