You mean like when Vegeta knocked goku with one hit even though he theorically shouldn't have fallen unconscious? like how goku got hurt by a bullet? or like when Sorbet used a very similar attack? or like when Frost used some poison that has no bussiness budging Goku? Or like when a measle heart complication potentially killed the man that was supossedly da legendary super saiyan? Or like when Picolo's attack pierced Raditz, who was much stronger than him (and Picollo straight up said it has the same properties)? Or like how they expicitly showed that Krillin's Kienzan, an attack from a vastly inferior enemy could hurt Napa?
U7 can't evade because he doesn't knows where it's coming from, he has different firing angles because of the balls, they don't know where the bad guy is because Goku has stated (on several ocassions) that enemies from certain universes cannot be sensed.
You have full right to complain about a show, but when you need to do the exact same complain each two episodes or so, it becomes stale, DBS already stated this to be a thing, ignore it or move on.
I don't like GOT, i mentioned it once and never looked back. I don't like Highschool of the dead, did the same.
