You are late to the discussion, my friend.

You need to complete all the story up to patch 2.55 so you can gain access into Ishgard where the 3 new jobs will be in.

To me early access(5 days), is for those who already complete the story line.

You do have to suffer Riot blade spam all the way to 50 and might have to earn enough item level to get into the last fight of the 2.55 story line. Was it iLv90?
