Not playing the tank anymore, couldn't seem to change my character on the forums. Got a lvl 21 Thaumaturge. So guildhest queues alone are having me wait 20-25 minutes.
Don't really care what is the faster, just some form of direction. The last main story quest I did was, where I unlocked the Airship, went around to the other two cities and unless I missed something, it just stopped. I did a few level 15 quests which just felt silly doing at level 19 then went back to Ul'dah. Couldn't see anything new there and went out in the world basically. Found a few quests in the East Shroud but that didn't last long. Have been doing the hunting log which I find cool.

Though looking now I do have a quest to talk to a guard outside of Sastasha.
But if I'm understanding it right, am I somewhat forced to do dungeons to level up? And are quests basically rare? My plan was just to quest to level, while doing Fates along the way.
