10-man comp: 1 tank, 2 healers, 7 DPS
Northrend Beasts 2.0. When one of the bosses is killed, he goes incorporeal but will continue to use one of his abilities through the rest of the fight, and the next boss spawns. Boss order will always start with Qiang but is random after that.
Qiang the Merciless
Stack in front of him to split up his cleave damage, then when he starts doing his frontal cone ability move out of it. The ability he keeps after death is Flanking Orders, which is Lava Wave if it were wider and made out of mogu; it marches across the room and will kill you if you don't move away from it. You'll have to move as a group for that one, since he'll still keep cleaving on every hit while Flanking.Meng the Demented
Switches between Crazed, which increases his damage dealt proportional to his current Insanity, and Cowardice, in which he wanders around and reflects damage proportional to his current Insanity. His main ability, the one he keeps after being beaten, is Maddening Shout, which is kinda like the thing that the faceless guy from Old Kingdom did; everyone becomes hostile to one another until they take enough damage from another player. Being grouped up in advance of this will probably help for breaking it quickly; just make sure that whichever AOEs you use to break Maddening Shout don't leave DoTs or annoying debuffs on everyone (Spinning Crane Kick/Arcane Explosion works best for this).Subetai the Swift
Spread out somewhat for Pillage (reduces damage/healing done by target and all within 4 yards, also increases their damage taken; this is the thing he keeps after death, so if you get him before Qiang then welp), Volley (turns at a player and does three frontal cone attacks at their location in quick succession), and Rain of Arrows (pins targets to ground with a Pinning Arrow, works like Marrowgar. Or Najentus. Attack the arrow to break them free).Zian of the Endless Shadow
Splash damage everywhere. He has Shadow Blast (works like Shadow Crash, apparently, except it's interruptable), a chain-lightning thing, and Undying Shadows (kept after death). Undying Shadows spawns an add which fixates on the nearest raid member and deals shadow damage to anyone nearby; when it dies, it drops a void zone, reforms after 30 seconds, and repeats the process (though when it dies the second time, it stays dead). So, have ranged players try to be the fixate targets for Undying Shadows and kite them to the outside of the room.
As you all know, we very nearly got these guys down 9-man! We can absolutely do it with 10. The first three phases are very manageable, almost easy. The final phase is where things get crazy. Specifically, we tended to die when Madness Shout and Mogu Wave came at the same time. In order to survive that, we need to group up and move together just like in the first phase. It shouldn't be hard, we've already done it lots!
The caveat is that anyone that is currently being followed by an add needs to stay OUT of the group. The add does an AoE around it which will wreck us. Also, if you see someone's HP getting low, stop attacking them! Killing each other won't help.
That's about it. We'll get these guys down and move on to Elegon!
For Science!
