Agree with all except the single elimination. 3 Matches is better.

Player 1 picks stage, player 2 picks stage, 3rd match( if needed) city.

For set effect, same with stage picking, but third round disabled. Equips cannot be changed so the players must make up their mind.

For the Spectator: I don't care.

Edit: I know most glunians prefer to play in city, but a few people like myself prefer forest. Same with Klunia, but the forest arena should be made available due to different play styles.
