Custom/private servers would be nice, but in my experience playing premades is nigh impossible. Even if no one does leave, which is rare, how can you wrangle 5 randos without voice comms? Maybe I can beat one of them but I’m not a MP god or anything. I suppose I could join a clan, but I don’t see the multiplayer as something I take really seriously as of right now. Is that a reasonable reaction to solo play?
We just pushed out a hotfix so that full-stacks will be paired up against other premade teams. We will continue to expand and work on this system over time to cover different group sizes.
Eventually, we hope to have some form of ranked matchmaking which should help with this a great deal.
We also plan to introduce voice chat to MP at some point during EA too.
