I have one more game to play to get my rank. If I don't play it and wait until next season will my MMR "reset" or will I still be playing around the same elo I was playing with to determine my rank?

i think it would be cool if they show your holstered weapons and knife especially if you have bought skins for them and wanna show off maybe it will add a slight tactical sense to the game if you can see that an enemy has a holstered snipe...
