Yes I know this is a FF game, story is important, yadda yadda, but from a business perspective locking new players behind nearly 400 quests (and this is just MSQ mind you: you'll still have to grind FATEs and dungeons to level up by yourself!) JUST to reach the new expansion, the place where everyone will play, it's anything but a good one.
Then maybe the progression time to reach the current expansion content must be fixed rather than a jump potion to be introduced ?
