This is sincerely bugging me at the moment beside the decentralized servers getting carried over from previous game. If someone else can confirm it is welcome.
After changing my server region to match with a friend, I can't see him in the lobby. On a whim, I changed my game's language to Deutsch, German. I can't speak German The result is a completely different game lobby with different players. I did not change the server region (evident by the room list).
Screenshots of people in the same server region with different game language
Game in German: the lobby
Game in English: the lobby
A lot more peopel...or 50+ people just get into/off the game at the same time. These two images are taken 8 minutes apart after I re-download the English language patch. So apparently, 93(server) x 8(languages) = 744 game lobbies that won't be able to see each other without the friendlist and invites.
This is not true MULTIPLAYER
