There are dungeons I don't like too, but instead of dropping and effectively screwing the other three people in the party, I just do what I can to make the run go quickly and smoothly. I'm usually queued for low-level as a healer, and a SCH dps'ing while Eos keeps everyone alive makes a huge difference in the lower level dungeons. Are they boring? Some of them are, yes. Toto-Rak is probably my least favorite and I get dumped into it a lot. The thing is, the other three people in the party are often in the same boat as me so I don't really want to dick them over by leaving. Call it a personal preference, but I just can't bring myself to do that to people.
