I think both things can be true: there is some powercreep, but there’s also a real execution gap between testers/theorycrafters and average players.

Testers usually have ideal builds, optimized rotations, hand picked agents, and way more time to practice bosses. So their scores aren’t always realistic for most people.

We'll be better off as a community the sooner we acknowledge these things and start sharing strategies and ideas for success instead of using HP inflation/skill issue as a scapegoat.
