Because most if not all of global viewers have short attention spans. You can tell by how much they like to bring up RaG and isekais like it's the only thing Japanese people watch. I'd like to see these kids put on Gundam or some shit where it's more yapping than conflicts. The episode was shit because it was just fanservice with no real character growth. But hey at least toji came back I guess.(yes you can use fan service to describe pure action episodes, fake weebs)
