Every bit of content in this game is designed, balanced, and tested based on the assumption that players doing this will not be using tools. Full stop. That doesn't mean testers and devs don't use debugging tools while testing to make sure everything reacts the way it's supposed to.
ah yes because checkpointing clearly allowed them to test the fight properly without leaving out the possibility of the main tank having a lingering magic vuln debuff that would get him instantly killed upon the boss autoattacking

maybe if they didn't cheat they could have caught this problem before release
