The problem isn't quite scaling, it's max iLvl, Endsinger used to have a similar issue where as the post patch stuff started happening and the max available iLvl increased, she started to die very fast after the LB3 sequence and you wouldn't even get to hear the Scions's lines, much less witness the desperation sequence that is the final phase, but they have since added a stricter iLvl 570 limit(for reference, Hydaelyn syncs to 550), and now the fight flows like it should.

Those two aren't even the only two that have this problem, a very big one to me is Thordan, who will die *moments* after his own LB sequence, and a bit of the narrative, that Thordan threw everything he had at WoL and we were still standing, so by that point he is desperately swinging while completely exhausted and barely able to move, is lost in the process, Thordan in general may need a whole rework, it's known that he can be beaten solo while sync'd.
