On consoles,yes why not on PC lobbys are a NO NO.
Why on earth is it a no no?
I play with 7 other RL mates and teaming together has been quite frustrating. Even hosting a co-op game I have to invite during the cut scene or i'll have to do it during combat? Really?
If we join a dedicated server there's no guarantee we'll all get on and then it might be in the final seconds of a match.
At the least we need something like the basic L4D lobby where we can all get together, decide whether we'll be co-op or vs, have the game randomly assign teams if we want, and then start the map/ campaign from the beginning.
This has been the only thing I think the game lacks. Yes, it needs a little more polish on some things but setting up a game as team seems to have been left out altogether.
