The players(collectively) have an enrage timer.

I tell you the true player enrage.

It is when the said player refuse to do specific boss mechanism in a light party dungeon where it is universally known it is their job, because they are busy doing their job, and start screaming and swearing to the point of almost crushing their computer be it PS3/PS4/PC.

I regret bringing this player to play with me even though I know him longer than most mainstream MMOs in the market.

I think people have forgotten that everyone must first understand mechanics and have high DPS output to burn a boss and ignore the incoming mechanics. They've begun to just skip straight to burning, even on first-time runs.
