(since the PC bug forum seems to be closed, i post this here)
when i try to start a pvp game together with a friend, we just never will find other players to fill up our lobby. the other playerslot-icons stay on “searching…” for minutes and minutes.
when we both queue up solo, we find players immediately. that’s why i think this is a weird bug.
the only way we found to do a very unreliable workaround is to start the game alone and let your friend join it immediately after… with some luck (1 out of 20 times) you’ll maybe end up in the same game lobby which is filled with other players as well.
it’s really very annoying that i just can’t play PVP games with friends.
