So this game has dps checks but we can't talk about our dps in game?

I've seen some very high-DPS players in PF for current savage. I have also seen a number of players who, to use a very simple example mechanic, refuse to disengage from the boss for aetherial shackles in P1S and thus kill the entire party;

I'm guessing rather than not disengaging, they were just late to their position or someone else was improperly positioned. Could still be because they're tunneling on their rotation or something, but aetherial Shackles should be completely safe to resolve in melee range of the boss.
