Lately I've noticed that PP enrages in most of the runs I join, and my Lordaeron DBM still has 30s left on its timer. That means PP has a 7:30 minutes enrage timer now, down from 8 minutes. This coupled with the nerf to abomination damage has made it very hard to kill now. You need everybody to be 6.1+ and to push damage as much as possible, locking out most of the casual players from this fight.
Some tips for this encounter is to use 4 healers, avoid all malleable and choking (as they represent a huge DPS lose and put unnecessary stress on the healers), melee stack on green ooze when it spawns as to no lose any second of DPS, minimize movement as much as possible and use prepots before the encounter. Even then it's a very close call to beat the enrage timer and takes several tries, definitely a harmful change for PUGs and new guilds, which continue to dwindle every month. It used to be a more mechanic-dependent encounter, now it requires exceptional damage too.
