I'd like to see seasons, and new areas added to the older zones, I mean everything below the latest expansion is basically forgotten every major expansion, ARR-SHB zones will stay as they are, and only new things will come in EW zones. Except maybe new materials to gather.. and new FATE's.. maybe. So I'd like to see them devote an entire expansion to populating the ARR-SHB areas with new zones, new quests, new towns, new enemies etc. So that if you decided you wanted to play the game again from the start, you would experience a lot of new content. Of course, Square-Enix don't want you to do this, their answer is "you have NG+ and fantasia, you don't need to play the game again" which i think is a missed opportunity, they might make more cash if they gave you a reason to play through again.

Most MMO's (and this is not really a complaint, just an observation) seem to focus all their efforts on end-game content, like keeping their long term players happy is the ONLY important thing to them. A lot of folk complain there's not enough new raids and such at end-game.. well you get a lot more content than low to mid game gets lol, can we have some new 20-70 optional dungeons maybe?
