The next large dlc we get should come with lots of new things for Crucible. Such as a 3v3 playlist that Scales with Glory in addition to normal Competive. Just as Valor rank has one or two random Crucible modes you can play each week instead of Quickplay, Competive should have that too for people who don't want to worry about being forced into a game mode their not good at. If I could select Countdown instead of it being random, then I'd have Luna already.
