Raid group I am in downed the fight tonight (we were working on Vortexer before nerfs), it is still difficult, people need to be aware of mechanics but it is more forgiving on time and damage, I honestly feel the fight is right where it needs to be now and what it should have been at the start. Little mistakes will cost you greatly, but 1 or 2 deaths now are not a guaranteed wipe on time when you are at the final boss.
