What is the fastest way to level a DPS class?

[TeraRamis]

My MSQ is complete, so that's really not an option. I have been doing the 5 roulettes a day for about 1-2 levels. But once that's done, I'm kind of at a loss. Nobody seems to grind fates anymore, so that doesn't appear to be much of an option (soloing fates isn't much fun). What else is there?
