Echoing that opinion that the Exaflare raidplan is not sufficient enough. Like the other poster said, should use same prio across mechanics and it doesn't indicate that there are more patterns.

It also doesn't explain that for melees they have to maintain max melee distance at all times. They can't simply move in a line (boss hitbox is circular) otherwise they will get clipped by one of the exa's. They need to be on the border of the second row of tiles from the edge.

PF will probably be better off adopting a melee downtime strategy rather than attempting this one and messing it up.
