If a competitive Elo/Glicko rating system is added, would it be possible to have a matchmaking queue as well? I've been off playing Tetris on tetr.io and they have it so that every ranked match is a series (First to 3, 5, or 7 depending on rating). Over there, a match takes ~10 minutes on average for competitive Tetris of all things. Series for every match would help rank players more accurately and you would be able to adjust your strategy for a certain opponent as time went on.

Here's a quick infographic on the Tetrio ranked system: https://tetris.wiki/images/thumb/4/4...n_-_Tetrio.png

Also, a low budget spar room would be nice. Something like only guns 10k gralats and under. At that tier, players have to really adapt to the obvious strengths and weaknesses each gun has.
