Biggest AoE avoidance fight since Council in BT?
Set up a bunch of markers around the room. Call out markers to move to as shit gets put down. Kill the dogs first and then keep the Shaman together to cleave. Tank swap every few stacks that Haromor applies to his tank.
At 85%, they will start spawning tornados that spawn more tornados and apply a DoT that can't be dispelled.
At 65%, they will spawn a bunch of slime adds at the feet of Karadris' tank that need to be kited and a green line of poison from Harom to his target. Move the poison line away from the raid.
At 50%, they will begin to spawn giant walls of elemental and a huge red circle of instant death. Don't get near these at all.
Just kite from marker to marker avoiding the AoE Olympics. Lust when they lust at 25%.
How can we clean this up a bit to make kills repeatable?
Get targeted with Foul Stream? Move between the bosses and the nearest edge of the active kiting area, most of the stream will go into the Orgrimmar buildings instead of the raid.
Earthbreaker Haromm's Ashen Wall (elementals that gib you) is cast perpendicular to the direction he's facing. Tanks won't always be able to position this but when not kiting or getting hung up on scene geometry they should be able to lay these along the sides of the kiting area.
