I don't like grouping either, but the DF makes it pretty painless. Truth be told, you don't even really have to talk to anyone.

As was said, most lower level dungeons will just get populated with high levels doing their daily roulette's - so they'll plow through it without so much as a hello. In, out, and on your way.

Primals withstanding, the forced dungeons are really just there to introduce you to the concept of party play.

However, once you hit endgame, you're going to want to get on the stick in order to go through the Coils. No way to avoid that.

Despite the fact that I have avoided it so far. I just keep going back to level up lower jobs in an effort to avoid it.
