I still wonder why this fight is called "hardmode" when it's doable with a pick up group. Heck, I tanked it in AF with shitty jewelry and did the interrupts with another warrior and backup monk.

You don't need a paladin for interrupts and you won't wipe if you miss an eruption.

Another anticlimax. If Bahamut's coil is as easy as these primal "hard modes" there's nothing left to do but quit and find a game with quality content.
