Some notes of my own, in no particular order:
Amber Void: We did this yesterday with a group of 2 greens 3 reds. Wasn't terribly difficult, mostly just a matter of endurance.
Good Grief: PVP trinkets remove the incapacitate. We destroyed her when we tried that.
Abuse the Ooze: Mostly just a matter of understanding how the oozes work and getting him out of that phase as quickly as possible. Once 2-3 of the little oozes are in the middle (I'm not 100% sure if it's 2 or 3), they'll turn into one of the bigger ones shortly. Generally speaking you'll be able to kill 3 of them, then push him into the next phase and there will be enough oozes coming to spawn the next 2. We barely made this one - I died right at the end, he ran over to the Hunter who popped Deterrence, and just before that fell off the boss started channeling his lightning thing and the DPS finished him off before it finished casting.
Consumption Junction: He does an instant cast attack that deals damage to the party and gives him one stack of Consume for everyone in line of sight. Easiest way to deal with it is tank him at the bottom of the stairs and have your healer stay out of line of sight, then just burn him before he uses the ability 3 times (about a minute and a half).
