This Is Awful.

Too bad you're not on Aether. I love helping fellow DPS with instant healer and tank queues when I can. I don't remember if you need to complete the mainstory in order to unlock the beast tribes, but they give you a decent amount of experience. That and hunts, if you have have access to them. You can do it while you're waiting on a queue and time will go by fast.

In that case I’ll warn you. In ShB there’s a level 79 story quest that requires you to beat a level 80 role quest to complete it.

I had the same experience with stormblood, all you can really do is make sure to hit level 80 before shit hits the fan storywise. I think I hit 80 before the trial with the super delusional guy whose name I won't mention in case of spoilers.
