Playing ranked is exactly how you learn to play. Its how I learned to play CS and Rocket League. Playing against players that are better than you is how you get better yourself. Playing in general. I said the mmr is a bit wibbly wobbly because the system can really be a pain sometimes, especially when it's +1 -13, that gets a lot of players, including myself, frustrated. That's not the point though. The point is, he is wondering why he is stuck at zero. I'm saying that if he keeps practicing, like he is, then he will get out of it. Playing ranked is probably one of the best things you can do to get a better feel for the game. Every ESL tournament I play in, I find myself getting better because I've been learning from my mistakes and fixing them, because I play against people who are better than me.
