We will not be using the 3 tank strat. Not necessary and with proper swaps and stack management on Tear Rift, shouldn’t be any need for a 3rd.
We will, however, use the Fatboss movement strat for Hasabel and alternate her between the entrance and the far edge of the platform to make sure melee can’t get caught out by overlapping beams and so we can position Hasabel ONTOP of the Transport Portals that she spawns to help with add cleaving and control.
Will need to see our timings to better sort out tank swaps as anything above 4-5 stacks will be deadly dot to a tank and possibly the raid once the debuff expires and explodes.
