if you payed attention to any of the story from 2.0 you would know why the expac is gated behind the story. Ishgard doesn't like outsiders and the story leads you to getting inside it would be pointless for them to point out that they keep there gates closed and then just let you in with out establishing why you were let in. So like everyone else you just gotta suck it up and do it if that's to much for you then #byefelicia you leaving won't affect the game in the slightest.
