You're choosing to ignore all the things that you can do while waiting for DF, so that's really your problem if you don't want to try to utilize the most effective way of leveling outside of a dungeon. If your FC isn't willing to help then maybe it's time to find a new one. You're playing an MMO, a genre that revolves around interacting with other people. If you're trying to circumvent that aspect of the game, then why are you here in the first place? Make friends that are willing to help you out.

And your "I'm not going tank or healer" statement only exacerbates the problem that you're experiencing. DPS DF queues are long partially due to that very reason. That said, if you've never experienced this problem in 14 years then I don't know what MMOs you're playing.
