Just letting you know as i am really tired to play on australian, chinese and japanese servers having ping 300+++ when i try to play through matchmaking system, and the real problem is not that i have to play with that terrible lag all the mission and have about doubled reload time on my weapons, but that i dont go to my "home" server (europe) after i leave the group. Even after relog i still on "foreign" server, so i must join some european player session to get back to my home server.
Why the matchmaking system is not looking for players from the same regoin and if there is no players in queue for some time there it goes to other regions?
