I said this like months ago, but GF map bans are still too strong. I'm fine with winner getting 2 bans, but the fact they can remove the opponents strongest and their own weakest maps is too strong, I think a way better system is:
Team 1 Ban -> Team 1 Pick -> Team 2 Pick -> Team 1 Ban -> Team 1 Pick -> Team 2 Pick -> Decider.
You still get 2 bans, first map, and a clear advantage. You can just remove a 2nd best (opponent) map or one of your weaker maps.
