Lemmings of the Light

I Choose You, Steelbreaker (The Assembly of Iron):

The hard mode of this encounter, but from what I can figure out not too difficult. The kill order for the bosses is Runemaster Molgeim, Stormcaller Brundir, Steelbreaker . The MT should be tanking Runemaster Molgeim and Steelbreaker while the OT tanks and interrupts Stormcaller Brundir .

The goal here is to kill the first two bosses and then nuke Steelbreaker, so saving cooldowns for the last boss is a must, as he does a debuff that will kill his target in one minute. Though he kills the tank in one minute, we have three minutes to nuke him down. The idea here is that the MT tanks the boss until 10 seconds before the debuff wears off and the MT explodes. When 10 seconds are left, the MT shouts out so that the OT can taunt the boss thus getting the debuff (it's instant). The MT should then run away from the raid and die at a safe distance (at least 15 yards). Then a druid should battle rezz the MT (or have a soul stone on the MT) so when the debuff of the OT is at 10 seconds, the MT can taunt and the OT runs away and dies. We should be more that capable to have steelbreaker dead before the MT would explode (probably even before the OT does).

Edit to above mentioned tactic: What I didn't mention with the above is that when Steelbreaker is the only boss left standing, any player that dies will heal the boss up for 20% (reduced by healing reduction moves like Aimed Shot/Mortal strike). So in that case it is very important that when the tank dies, he does that at least 15 yards away from anybody else, otherwise he'll receive multipe heals of 20% of his maximum health. Also, per player that dies, he get's a 25% increased damage buff. With that, the idea is to have the raid on one side of the boss and the other side for the tank to run to and die.

The group should be composed of 2 tanks, 2 healers and 6 dps, meaning that this will be an ideal achievement to do after XT-002.

Disarmed (Kologarn):

The goal of this achievement is to kill both arms and after that Kologarn in 12 seconds from the kill of the first arm. I've read up a little bit about it and it's a bit buggy (still). As an arm is killed, the boss loses 15% health. But if the boss is below 30% and then both arms are killed (resulting in the death of the boss) you may not be awarded the achievement.

So the idea here is the following. We keep killing the right arm 4 times, leaving the boss with 40% hp. While killing the right arm, we slowly dps down the left arm until about 5%. Once the boss reaches 40% health, we dps the torso (main boss) to about 31~33%, then kill the right arm, finish off the remaining 5% of the left arm and then finish the last 1~3% of the boss his health and we should get the achievement.

Crazy Cat Lady (Auriaya)

A pretty simple zerg down tactic here. Mainly two ways to do this. One is to have both Sanctum Sentries on the OT and kill the boss before the debuff stacks get's to high. Or dividing the Sanctum Sentries between the two tanks and zerg her down. Depending on the setup, I'll try the first tactic and if that doesn't work the second one.
