I have gotten this on garuda as well, but it isn't limited to the primals.

And I suspect it is often the same tanks though, because I had this happen three dungeons in a row, with the same tank. Two wipe dropouts. First dungeon was CC. Made it to the last boss. Wiped two times because the DPS were new and didn't understand the in/out/run mechanics. They had just figured out the in/out part, after I explained it again, when the tank rage quit.. with 30 minutes on the clock so plenty of time for the DPS to figure out the rest of the fight since we were continuously getting down to 40%.

Next dungeon, I queue up for DD, my first time because there is no tank ever queued for that one for me. Same tank. We wipe once pre-first boss. Make it through to the second boss. We wipe once. Tank drops.

I queue up for Stone vigil. Same freaking tank. Two wipe. Tank quits.... I don't even know what to say to that. The guy just failed three dungeons in a row, wasted hours of his time, and hours of other peoples (because tanks rarely queue in progress), rather then wait for the other party members to figure out the fights.

The only reason I didn't just quit the third time I saw him was because of how long the queue is for the DPS and it wouldn't be fair to them. But it ended up not mattering anyway.

That right there is why there needs to be a better lockout punishment system. That tank should have been locked out of DF without a premade at least for more than 15 minutes, I would say a day at that point. Anyone who quits habitually like that should be getting their own group together outside of DF, rather than waste other peoples time.
