The fact that you don't enjoy or prefer something doesn't mean everyone doesn't, or even the majority. Most final fantasy players enjoy storylines, that's why they play FF in the first place, and that's obviously one of the main "rewards" a final fantasy game does and should offer.
i am a FF players, i enjoys stories, i dont spam enter buttons during dialogue, and did all 3 cities missions.

but, do tell me why are alot of FF fans out there doesnt play XI.
offering only storyline isnt really a good idea on a game with MMO genre.
