Black Temple Timewalking Relinquary Broken

The gauntlet never stops after you start it, and waves of adds come through the first phase and it can't be healed through. The only way you get through it is if you get lucky and you don't get that many gauntlet adds. Phase 3 is an insane dps check because the aura deals half your health every few seconds. Eventually the raid runs out of healing cooldowns and dies. Really wish Blizzard would have tested this raid.
We were able to get through phase 1 with disc priests and no or little adds, but at phase 3 we wiped at 50% every time. Something not right there!

I hear mother is another one thats broken, but we didn't get that far.
It seems like the first phase of Reliquary is doable even with adds by using disc priest and shield spamming, but phase 3 is pretty much unkillable.

Mother is beatable, but her chains are quite overtuned even in comparison to the original raid. It's helpful to stack classes with teleports and avoid classes with low mobility, because the chains kill you in roughly 3 seconds.

Council seemed fine. Illidan was also fine except the flames of azzinoth seem to be overtuned and hit so hard they make Illidan look like a kitten in comparison.
