I would really like it if they took some ideas from how the XRD lobbies are structured, 8 players to a lobby with the ability to either find up to 4 stations to play in 1 lobby, or all 8 could cram one setup and take turns while spectating matches, if u choose to solely spectate u could do that too, and ur turn would be skipped automatically.
What I don't like about king of the hill in MK9 is you really didn't have the option to chat it up if u didn't have a mic, nor could u select to automatically have ur turn skipped, same with injustice, these options are must have, for casual matches, and online tournament matches alike, no one wants to have to beat up a none moving player just to get to an active player, too much of a hassle, also in XRD it has an automatic 10 sec timer that triggers in the lobby if a player fails to start up a match because of AFK, that is also a big help.
