The UI design for casual lobbies really is a masterclass in cluelessness, isn't? After trying to figure out what was going on and not being able to get in game, I had to look up how the thing worked. Apparently it's not winner stays on automatically, but each new match one of the two players has to choose to give up their spot. This means you might not get to play.
There is a spectator mode, but you have to 'pick a seat' to watch a match, assuming that then players haven't readied up, meaning there's no seat to pick. And of the ten seats for spectators, two are reserved for the people playing. Also for some fucking reason one of the players is called ' Captain'.
Is that right? Even after reading about it, I couldn't understand it.
