Not Support Public Matching on COOP MODE?

[Mikan]

If want to play COOP MODE, only invite friend ?

it does, by theory...though I never managed to find one.

It does work, But there aren't many people looking, most people only create lobby and play.

I've joined peoples lobbies and have had people join my lobby as well, so it works.
