I see your point about ESEA having problems since it's only down to two divisions, pitting high level players against low level players. I also see your point about us paying for services from ESEA that we no longer need such as TF2 scrim servers, pug servers, forums, and a kind of non-existent anti-cheat that we're not confident is actively being developed.
Just brainstorming here as I think it is an interesting discussion
If you truly think prize pools are not necessary to motivate players to continue playing this game, why not put more effort into developing UGC? Why not work with the UGC leadership to turn it into the league that you want? The reason I think UGC could be a prime candidate is because they already have infrastructure and an established NA player base. If you can get high level TF2 teams to play in UGC, you could probably get the rest of the NA scene to switch over too. I think the difficult part of getting the high level TF2 teams to switch to any F2P league is the lack of incentives, but I'd be interested in seeing what you think would motivate these teams if you feel prize pools don't matter.
If UGC is not a good option, why not work with ETF2L or other established brand to bring an F2P league to TF2? Would it be too much work with no payoff? Would you be able to recruit a large enough team to run this league? What is required to get it off the ground?
I'd encourage you to pursue your goals if you feel it truly is the best thing for TF2.
