Also added an additional rule:
Once a map is picked for a round, the team that selected that respective map will confirm their team setup (who is playing slot 1 and 2) and the lower seeded team will then proceed to pick the slot setup they wish to play.
This is to stop perpetual lobby sim with people swapping who is where back and forth. People don't need to follow the rule robotically, just consider it something to cite if the people you're facing start dicking around in the lobby. If everyone plays nice then just ignore it.
