If Lahabrea had packed this much heat-no pun intended-in his first boss fight, the Warrior would...probably still get bailed out by Hydaelyn, but at least the dude would be somewhat less forgettable!
I like to imagine that the writing team lamented how Lahabrea was such a wasted character, so when Endwalker's MSQ made you time travel to the world unsundered, the team saw their chance and locked the hell in.
