I had a Hunt mark that was in one of the FATEs deep inside the Amalj'aa area. There must have been a lot of people last time. On my i96 Warrior (out of Defiance) I started hacking away at him and only just managed to finally beat him with 4 seconds left. This was due to the massive HP pool from the previous round of participants, and the adds that kept patrolling there and aggroing on me mid-fate and killing off my chocobo, meaning I didn't have any additional DPS.

Perhaps they could link the timer to some kind of debuff that brings down the defenses of the boss the less time is left on the clock. Like at 5 minutes left the boss takes 30% more damage and does 10% less, or something like that.

(Also perhaps they could look into the adds on It's Not Lupus because there is NO WAY to do that as level-synced level 30's as a part of 3, even with chocobos, so how is anyone supposed to get credit or get the achievement for it?)
