Is it possible to play with friends without the rank to be modified ? To play some non ranked games ?
how to create map without effect on rank ?
There are various options that cause a game to be unranked. I think adjustable speed might be one of them and that won't affect anything material about how the game plays.
deactivate the "dummy drone" on the top right of the unit list in a game lobby. It was introduced to easily unrank a game.
