I mean, U7 isn't winning this tournament, so I wish they focused on U7 less. I honestly don't even think U7 is in the final 2 anymore, I think Jiren or Toppo makes it past U7. That's my opinion, not stating that as fact.
If U7 wins this tournament, then sure focusing on U7 is right, right now it doesn't feel like U7 is winning, and if they do it's bad writing,, it feels like U6 is obviously the one winning, that's how things have been developing, and I think it'd be more interesting if they focus on a dynamic between the winning universe, U6, and a new universe, U11.
U6 has taken out most of U11, the universe hyped the most, yet U11 hates U7 because they're the main universe and the one we should care about. I'd rather have seen U11 form a hatred for U6 instead, it'd be more fitting with how the tournament is going, yet stuff like that is held back with this logic that Dragon Ball is about U7. What if the exhibition match had been U6 vs. U9? Hit, Caulifla, and a Namekian or Frost. A Hitman who kills people for money, a saiyan who enjoys fighting plus in charge of a gang, and we can assume the Namekians are going to be evil, and if not that's where you throw in Frost, that's 3 people Toppo would hate, and form a rivalry with instantly, and it's more believable than just Goku, and he could form that hatred as well, since the GP would tell everyone during the exhibition match that it was Goku's idea for the tournament, and since it was Goku's idea, Gok would probably go with even if he's not fighting, to scout the competition, maybe he could convince Gohan as well, watching some good fights might get his saiyan blood flowing. A Toppo vs. Goku fight might have been more interesting if Goku never thought Bergamo, because it'd be more fresh. We wouldn't have the Buu fakeout hurt as much. The only thing that benefitted was Gohan's fight with Lavender, but they could have saved that for the ToP, only it's more onesided with Gohan having Ultimate.
You can still have Gohan be badass, Piccolo, Roshi, and 17 do cool stuff, but honestly I wish the big rivalry was 2 different universes that weren't U7, we've had 600 episodes of Dragon Ball focusing on U7. And right now the outcome looks like the 18 episodes focusing on mainly U7 for the buildup of the tournament, could have went more to U6 and U11.
