Finally I can contribute to this thread.
Today I was running mentor roulettes both for the mount and because I enjoy the variety. Normally everything goes without a hitch, but today was the rare exception. I join in progress and it turns out to be Dohn Meg at the second boss. It's just me and two DPS, a BLM and a RDM, who are having a massive fight with each other. The RDM is accusing the BLM of just using ice spells and the BLM is responding that it's their eight-year old sitting on their lap playing while they watch. I'm just watching the fireworks while I wait on a healer to join in the madness.
Eventually we get one, but at that point the BLM has had enough I guess and tries to votekick the RDM. I hit no, but it went through anyways and we get a DNC instead. I go ahead and pull and, yeah, it's either their kid playing or this is the worst BLM in existence. No fire spells, no ley lines, nothing. Gets hit by every aoe and ability. Thankfully the DNC and AST were total chads and we made it to the finish line.
I took a break after that.
