I'd rather it just be forced at minimum ilvl, and boss HP be increased. Even my very first time in there on the day after release, we burned through most fights too quickly to see all phases. It was only after running a friend through it, as a duo, on PLD, that I got to see everything.

And, revise the cutscenes. If it can be covered during the fight, do so. It it's fluff text, cut it. If the reluctant pause is longer than necessary to mark such a pause, quicken it. Hasten transitions.
