One thing I never understood (I main WHM but have PLD @50 leftover from ARR), is why do dps intentionally sabotage themselves at times by pulling stuff like this? I mean, I did my time waiting in dps queue on BRD and NIN, and unless the tank was god awful - almost bot awful - I'd grin and bear it to get the thing done. It is almost like they get into a duty and forget the amount of time they've waited or, even worse, berate or don't play as a team even when almost done, potentially being kicked before even finishing. Just... think before you act, and act as you'd like people to act towards you.
