I assume most people are queuing into dungeons for selfish reasons. It's probably pretty rare that someone is doing a dungeon run for no personal benefit.

Even the TC has made it pretty clear that they're in it for the Anima grind.

So for people to turn around and call other people self-centered despite having the same skew in motives is hypocritical. You're saying that you're entitled to your selfishness but they should sacrifice for the group.

Do I leave dungeons? Yea. I try not to do it if I queue into something like Sastasha or anything with a green leaf or bonus (even if I don't care for the bonus) but will I leave a 60 roulette if it rolls Aethereal Chemical Research Facility with no bonus? Yea. Will I leave a Ramuh EX mentor queue if the group really can't clear it and refuse to vote abandon? Yea.

The reality is the roulettes are not balanced right now. You can queue into a 1 minute guildhest, a potential 40 minute AV wipefest, or a full lock-out of hopeless Ramuh EX wipes before an inevitable abandon out of the same roulette. ACRF takes a good ~25 minutes whereas something like Fractal is done in ~10. When people value efficiency, of course you're going to have leavers.
