Why encounters with a difficulty slope are bad

[Krr]

Saying something is bad design is practically a meme at this point, a dogwhistle whenever someone personally struggles with difficulty but can't take responsibility for it.

Remember that time the game's lead producer apologized for T-EX because he didn't realize how unfun it was for players outside of Japan's 5ms ping internet infrastructure until he tried playing the fight on a trip to Australia and got landslid repeatedly?

Yeah, no. Some fights are just crap design.
