What's important to point out here is that you not just "Play a Game". You are playing a game based on what probably is the most advanced matchmaking algorithms ever made. It seems that after the critical mass of about 30k players during beta, every single game was a long and thrilling match against a fully equal level opponent. When the beta started I got matched into copper league (the rock bottom) and when the beta was over I played in Diamond league (the top) and it was all made possible by simply hitting a play button and playing against the perfect opponent so that I learned something every game.
