-Cull the cast. Way too massive, it's as bad as young justice. Should consist of the 5 founding members, Spider-man, Ms Marvel, Nova, Viv, and Brawn.
-Every member of the founders can bring 1 additional member to add to the roster, So Miles could bring Bombshell, Kamala could bring Becky or Amulet, Viv could bring Nadia or Iron heart. And for members like cho and Sam who don't have many connects their slots could just be extras like Laura/Wolverine, one or both of the fantastic 4 kids, or the power pack, Starling etc. 10 members active is fine with all others going into reserve to be swapped in and out as the story demands.
-Roxxon trying build their own set of 'hip' heroes is fine just nix the outlawed/Kamala's law plot line. It was gutted because of covid and it's over stayed it's welcome.
-Emphasis on smaller scale crisises. Avoid universe ending crap, the separation from the avengers is the champions should always be looking out for the little guy, the fringe. Avengers are broad stroke while the Champs are precision.
-Keep message of optimism, friction in the team can exist but they shouldn't be having a civil war.
-They should promote unity in the super hero community, having mutants, inhumans, prominently on the team.
-Another solid antagonist besides the corporations would be good too.
