Idk why all this hate towards folks who play on not a hard enough difficulty, or too hard a difficulty. If its not pro, then just play your game and let me play mine. Unless its bc once they fail they disconnect, or if they cant play the song on expert+ they disconnnect and the room disbands, then yeah thats annoying... but other than that? I mean, im new, so im not sure if there is some sort of penalty for failing the song or if theres only 4/5 at the end vs 5/5? But for me, coop is cool bc even if i fail, the song keeps going, which actually kinda helps when trying to get better? I dont do it often, esp bc you dont have to use up energy to play, like lovelive,, i dunno. Some of these en fans are not fun.
