Hard Enrages are one of the main issues with this game when it comes to endgame to be honest. Why everyone only cares about DPS. Just pure stupid game design.

Should make them soft enrages. 10mins or whatever hits. Bosses get a stack of dmg taken -10% and damage dealt +10% then an additional stack for each 30secs - minute after that, to the point where it is impossible to kill.

Not the oh well you are at 5% guess what though... you had a Ast, nin, and rdm in your party so you timed out. Do not worry though you can wait 3 weeks longer then groups of equal skill to clear it or play the meta jobs.
