This is a somewhat decent idea, however it should be in the cash shop. Later on in the game, like in TW servers, maybe Daneos can gift everyone one lvl 33 stone to use for any character.
It was in the cash shop on the TW servers? XD i never saw those stones on the cash shop, but if was in the original DBO before, why not put again? Still, everyone need to have the chance too to get the stones without spending money, and i will miss the time when the more you played, the more you could get nice items for free x3 but is okay, the only thing i want is play DBO like in the old days and buy the Trunks Dogi.
