I'm almost done with my first arena playlist, but before I can finish I need to know whether challenges in a mixed playlist will become solo or co-op. Should I make one for solo play and have it be easier for co-op, or make one for co-op play and have it harder (or not beatable) for solo?
Also if I put challenges in my playlist, will the game auto assign the playlist to be co-op and hosts will have to wait for a full room just to start, will it assign solo and the whole playlist can only have two players, or will it allow 2-4 players like any other arena playlist?
