I love seeing this as a blue mage main lol. I was waiting and theorizing how they handle this fight when the lv80 update came out and was thoroughly disappointed when their answer was: no. Glad too see blue mages just decided that naah Id win this fight anyways.
So basically just have four people kill themselves, the remaining 4 rez them, and the dead people take the rez as he's casting the spell so that they're in limbo and thus can't be killed by it?
At 4:25 he casts an ultimate attack with LB4, this ability is coded so the ONLY way to survive it is with limit break 3 from a tank, BLU cannot use Limit Breaks.
