Are you unfamiliar with the concept of "less?"

Like, there's not a whole separate game being proposed here. Some numbers, for some people, in some matches, will just be... less. How to play works exactly the same. It is the same game. And this only needs to affect the people who are already kicking ass.

Their contribution will still be critical to their team's victory. It just won't be enough to single-handedly decide the outcome for all nine other players. It will be... less. They can still be the greatest contributor. They can get in-game recognition for every clever decision and make their brain squirt the happy chemicals. They just don't get as much per-action as the guy who's figuring out what DoT stands for.

This isn't high witchcraft, or some kind of paradox. It's grading on a curve. It's "handicapping." A boring and typical adjustment in actual sports, even at higher levels.

And again, it only has to work in the dirt leagues, because the goal is keeping assholes bored. If you play super duper good, and get bumped to a higher rank, and play with other people of that rank... none of this applies. Nothing is different. High-level play between high-ranked players would remain as sweaty as you can imagine. If someone pops enough adderall to see through time, and completely ruins a ranked lobby full of gold players, who gives a shit?
