While I agree that cyber fighting leagues has it's problems with planning, I don't entirely agree with the factor of supers and the potential solution.
With regards to supers, that's really easily policed by having an authority of any sort that warns players or disqualifies depending on how things are going and if the warning was issued live or not. Of course, all the same, it is possible for supers to go completely unwarned, but that's a problem with cyber fighting in general and not just leagues.
As for people trying to do everything they can to win - idk about you but I kinda like that? (Within the context of properly responding to my moves of course) If someones going to challenge me to competitive fight, I expect them to beat me unless I bring my A game (unfortunately, most of the so called 'competitive, dominant, alpha' turn out to be the total opposite. Nothing against jobbers or subs, but I prefer people just being upfront about what they want rather than trash talking me for my size and then dropping to their knees 3 moves into the fight).
But even beyond all that, I think the bigger issue is that your solution wouldn't quite work. Most people don't really want something scripted, a lot of people enjoy the uncertainty of a competitive match. Jobbers want to be beaten up time and time again, not just a one off that drops them out of the league. Dominant fighters are genuinely hard to come by and the ones that do, generally prefer to beat the spirit out of someone, not have it handed it to them due to following a script and being a character of sorts. So whether you've got dommes, subs or competitors in a league, I don't really see this format suiting any of them.
Not trying to bash the idea, and of course its great that people are suggesting ways to improve things (Good on you girl!!), but I just don't see it replacing typical cyber fight leagues as such but may have a shot at appealing to a very specific niche group of 'fighters'/actresses.
