This tank (Blue) clearly woke up one the wrong side of the bed, or had a very bad day... or are genuinely a horrible person :^)
I really wanted to be sassy and ignore everything the tank demanded ("you don't pay my sub" was something I really wanted to say. It HURT to not say it), but at the time I wasn't sure what the SAM and WHM's opinion on Salty McTanksbad was and since it was a little after 10PM, I didn't want to risk a kick.
They were pretty quick leaving the dungeon. Like they could sense a storm ridicule coming their way. We were not kind...
By the way, the tanks first outburst was over nothing. I just did Fleche and that was it. Tank still had hate on the one Phoebad and stopped mid-pull to scream. No idea what they were on about regarding the AoE's of the final boss (they even had the boss facing the group at one point, so... pot meet kettle).
