[FOR HEALERS AND RANGED] THESE ARE FIXED POSITIONS. SHORT/LONG FUSE AND RELATIVE NORTH DO NOT MATTER.

Ranged and Healers preposition at NE and SW on corners. It is always the safe spot.
Tank/Melee short fuse goes out a little past the cardinal marker.
Tank/Melee long fuse stays center.

Ranged rotate CW. Healers rotate CCW. Same corner spot.
Tank/Melee swap. Long fuse going to opposite cardinal.
