League doesn't solve it. People will complain regardless. GGDPLeague is a perfect example. It turned out fine, but no matter what, people will complain. Whether it be "the server locations are rigged to benefit Myers' ping!" - to - complaining about the map selection etc... - The work put in is not worth it. Especially now that the game can hardly get a 3 versus 3 game going.
As for tiemaps, win 2-0. And I've never had a problem with tie maps. I guess it's cause I only go to tie vs vT or MLG for the most part. And we can usually agree on pforest/carp/sass/ren etc.. so it's fine. You'll never solve this problem though. No permanent solution will ever be put in place. Pretty sure this argument has come up many times before too.
