So, as it's come up a lot in this thread, can I just ask why any DPS (or anyone) would WANT a full clear for exp? "They have to wait a half hour/hour obviously they want their exp" has come up a bunch, but you get less that way than doing a speed run and then going back to Fates/Levequests.
Like, okay, fate farming is boring. Sure. And Levequests get tedious. Plus you can't learn how to play your character in a party without doing dungeons. So yes, clearly you want to do a lot of dungeons leveling. Fine. And when you do them you want exp.
But here's the thing: You get a lot of exp for dungeon completion and for boss kills. You get pretty good exp for random trash too--but the exp per minute is going to be lower for random trash than just doing fates or leves. If you're doing full clears, you are, therefore, slowing down your leveling, not speeding it up.
As someone who has started leveling a bunch of DPS classes to 50 to kill time until expansion, and who mains a DPS class, I actually hate it when another DPS asks for full clear. It just makes it take longer for me to get to that next job/class quest that I'm always trying to push toward as personal milestones. With the semi-exception of letting seeds hatch in AV. If you do it right it doesn't really take any more time and it's 10x the exp. If you're killing seeds off for your 'speed run' you're just kind of a dick. But that's the only exception.
On topic: Anyone who read the thread would see that the DPS ran ahead to pull, made a 5 mob pull into a 9 mob pull, and then refused to use his 'one AoE', making it take painfully long. Whenever I get in groups like that I generally tell them to have fun, apologize to any innocent members of the party and leave. If I'm healer or tank I try to remember to ask any innocent DPS what their server is so I can party with them and requeue when I'm able to make it up to them if possible.
I think pulling mobs off the DPS rather than letting him die, and saying, 'Okay we can do a full run, but only if you actually use your AoE skill' is actually going above and beyond what could be expected of anyone dealing with that level of toxicity regardless of their role.
