Often times, the low population in Spartan Ops results in being partnered with just one person, rather than a full complement of players. This also reduces the game difficulty from Legendary to Heroic.
Given the upcoming switch to Mythic, I’d like to see the matching system tweaked so it always creates teams of four players.
Search times will increase, but I think it will make the game more enjoyable. Additionally, it will ensure the system doesn’t throttle back the difficulty level or hang people out to dry when their lone ally is AFK, griefing or decides to quit in the middle of a Hunter hoedown or hairy Fuel Rod Gun furball.
