I highly recommend people try to befriend as many others as they can. It makes the grouping activities exponentially better, AND you don't need to worry about the DF queue (much). Plus, if you like to go in blind, it's a fun learning experience... usually. Before you know it, you (anyone) might find yourself leveling a role that you would never have bothered to do for random DF and, most importantly, having fun doing it.

It's honestly so much better, that it's probably best that people forget that DF actually finds random people for you.
