The way they're handling power differences between characters is becoming fairly poor at this point.
It reminds me of trying to write Superman into a team. It very often results in clumsily making him weaker than he should be, or clumsily making those around him stronger than they ought to be. Power scaling gets weird, nonetheless.
Goku has become that Superman-like character, where the limits of his power are poorly defined. So Super Saiyan Blue is a Earth-shattering transformation in some cases, and 'Super Saiyan +' in others. He's desyncronized with everyone else, except maybe Vegeta.
