I got this Feat a few hours ago with 2 Leaguemates and 5 players from LFG. I have to say that it wasn´t easy for us and took us several tries, but it was a really fun time, especially because those last seconds of the fight were pretty EPIC!
Well done! We popped this feat and the first boss feat a couple of times today randomly when spamming the raid. Wish the feats were designed so you actually had to go in there with the feat in mind rather than them just popping naturally. Oh well, was still fun.
I noticed that if a trap ever did get activated it was usually in the West quadrant whilst we positioned our tank in the North or South. We did a couple of runs where the boss got burned down so fast that a trap didn't activate and that's how we usually got the feat to pop for those that needed it.
