For the love of God people read what has been said to you!
As nTraum and others said, ETF2L's backend is pretty much spaghetti put in a bag and smashed up to high heaven, so making a big change like replacing our ruleset would be much harder than you'd think. The website is tailored entirely around two maps a week with barely any thought (if any at all) put into being able to change that even remotely easily. Changing it would just confuse stuff a little bit too much.
Our ruleset really isn't that big of a change for NA players, and playing two maps really is not difficult to be honest. It keeps things fresh and you have an entire week and the pre-season to practice these maps with your team. Not only that but wildcards should seem like a godsend to you guys after some of the shit I've read recently about people being unable to play and things going way worse than they should after a league refuses to let you play just a few days after.
Everyone is in the same boat so it isn't like you have a disadvantage, and one season is really all it would take. Not even that if I'm honest, because you'd probably see after just a few weeks that it isn't as different as it seems. Personally I'd love to see you guys over at ETF2L and I hope you can at least look at how smoothly the league runs for now and ignore the fact that you (the top teams, of which there really aren't too many) don't get (for now) all the benefits you feel that ESEA gives you. Especially considering the fact that as you all know the negatives of ESEA vastly outweigh the positives.
If this does actually happen I feel like ETF2L could grow to be much much better for both regions and that could very easily lead to all of the things that you feel we're lacking being added or replaced with similar perks in the near future. tl;dr? Give it a chance, you might enjoy yourselves, and it might vastly improve the scene of our lovely little shitheap of a game.
