I don't want to play another quest grinder. There are plenty of games out there that do it better than FFXIV can ever hope to.
I may be reading too much into the translated letters we get but Yoshi keeps giving me the impression that he wants this game to have MANY avenues to get SP, and for it to be less of a grind game. So I agree with you that I don't want to see this game go to a purely quest grinding structure. I think it could only make the game more attractive to a larger amount of players if there are several viable ways to obtain SP.
