I’m not sure if this is a Beta-Only thing, but I think it’s totally whack to have Matchmaking be random gamemodes only. MCC is already up and running with the perfect filter for what kind of matches you want to join, even going as far as letting you criss-cross between the games and gamemodes, only for Infinite to take 10 steps back and only put you in random matches of either arena or BTB. This is starting to get old, specially when compounded with the slow--Yoink!- battlepass progression being bottlenecked by ultra-specific challenges that stay unfinished because we can’t even choose which kinds of matches we’ll join.
While you’re at it, open up public lobbies for custom games 
And fix the -Yoink!- battlepass, let us get XP through just playing the game and doing good at it… Like MCC…
