In Game Lobby

When everyone joined to the game lobby and me was the first one who choose a lane, there has to something wrong bug because the other player sad she/he was first. It happend several times. And sometimes happend becouse I joined the room and chose a lane, than another player joined the lobby and she/he wont see what I choosed, because the late joining. Why its so complicated? And vica versa. That was incorrect thing. Mostly thay sad Im noob or other unlikeli words. And If I wont leave the lobby than in the game they are unfriendly... And If I leave the game lobby Im the one who punished with more than 5 minutes... and so... That is do redicilous conflicts.
