I finished every mission in the game and just want to help people now. The problem is I never know which missions they need and the lack of an ingame chat doesn't help with that. I also have no idea which rank they are on, because I don't remember the symbols of the ranks. Now when I choose "online" I have people join me and don't know which missions they want to play. That's why I just want to join their game, so they can decide the missions. Sadly, that's not possible at the moment. We have to be able to choose if we want to host a game or join someone else's game.
