Our Sessions feature is already getting an upgrade with the possibility to mix the teams composition between rounds.

By default, after a game, players are suggested to join the next round in the same team and at the same role.

But you may want to mix roles and even mix teams between round. This is now possible with an option in the Session settings to allow players to change role or be sent back to the lobby for the next round - from where they can select or join randomly another team/role.
