The 5th run I had in Qarn we had a new DD and an "experienced" tank/dd as well as me. I love dungeons so naturally I had already done Qarn a few times on my other class and a few on the healer already (even though they were bad runs).
At first it seemed awesome, the tank held aggro & I wasn't constantly running/CC'ing the mobs and then we get to first boss where the tank dies from a "Final Sting" (new DD was an Arcanist, learning the best way to deal damage to the bee's still). I used swift cast and raised him instantly, healed him back up and we were good - happened a second time where I was low on MP and couldn't spare the time to help DPS the bee's, I had however enough to Raise and then pop a hi-ether to heal him up. No wipes.

After the boss was killed he stopped for a few seconds (to type, I presume) and wrote:
"If no more bees in dungeon i will leave" "need focus"

He left, probably my fault for questioning what he said. So we continued to clear trash up until the next boss. After about 15 minutes a new tank had appeared in. We were ecstatic and welcomed him/her warmly.

This person ([B]Psxpert Sylph[/B]) was a troll. After he explained he was here for some mobs for his hunting log, we all apologized for clearing them and he still seemed enthusiastic. :) When he arrives at the Temple Guardian we start the fight (after Establishing he knew the fight). He doesn't hold aggro at all, and starts chasing all of us and we wipe a couple minutes in. He said he thinks he may have mis-targeted. We weren't fussed and said it was okay. Second wipe he said his provoke was on cooldown. We weren't fussed. Third wipe he said he might not be able to reach the Temple Guardian. Fourth wipe he said his gear was not good. Fifth wipe he said his gear was badly damaged (fair enough lol). Everyone was keen just to get this boss done, we had 19~ minutes left on the timer. I check out his gear, it's all synced down from level 47-50.
I ask if he's trolling us, he said no. Then I said "please hold aggro this time". Wipe.

He did not use a single skill in the last 3 wipes at least. Simply 'auto-attacked' the target.

So at this point we're worn down and the Arcanist says: "Should I use Titan?".
The tank replied: "i think wind work better against earth".

I go into the ring for one more round with the group and sit down, the other two players essentially did the same as the tank asked for 5 seconds to get aggro this time around..

With 12 minutes left on the timer we've wiped again, and I ask "Why are you trolling us tank? That's not cool :(" "I think we would be best to leave and sit the cool down period guys.". The tank replied: "I'm not trolling, fine, i'm leaving." At the point I clicked "Leave" in the Duty Finder window.

I have screenshots of most of that because I honestly thought after the first two wipes that we were being trolled. Turns out we were.

Seriously, why would someone be such an ass? I wanted to stick it out for the other two players, they were keen to get at least this boss down. But that was just horrible.

The dungeons before that were just players not listening - stuck it out until the end for those anyhow. The 6th run of Qarn was with a friend from the FC and two awesome other players. Thank goodness for that.

So good on you for reading this far, sorry about the rant.
