Forced stops are honestly grating and boring design. The trash in endgame dungeons don't do a damn interesting thing and is somehow less of a threat than the trash in midgame dungeons.

That said, I don't feel that speedruns are either a problem or a solution. They are a symptom of bland dungeon trash design. I actually enjoy most of the boss fights but I can only think of a few pieces of dungeon trash that actually interest me endgame, and many of them are no longer relevant.

If S-E wants to stop speedrunners they should actually make the trash and environments threatening and interesting enough to A) not be speedrunnable in the latest patch in most cases, and B) Not bore players to death fighting them.
