First, position your main tank and one healer near the 4th area. Put all dps and all but one healer at the 1st area.
The Red X is the tanks position
The Blue X is the raids position
Those are the positions pre-pull.
These are the positions everyone will run to as the tank pulls the boss:
The Red X is where the tank and the melee dps will be standing.
The Blue X is where the raid will stand while healing or ranged DPSing.
The Green X is where Heigan will be positioned.
With that, all you have to do is stand and DPS/Heal until the first real Dance part. About 2 seconds before Heigan teleports, you should ALL run to the Cyan X's.
Once you complete the dance, just run back to the original places shown in the first picture and repeat.
Hope this helps someone, and thanks for reading^^
Also, before people start saying this should be in guides, the exploit is that you should NOT be able to avoid having to do the first part of the encounter.
