Matchmaking in Normal Draft
What is the matchmaking system in place causing me to run into a huge win streak, followed by a huge loss streak? I'm aware that ranked has a different matchmaking system in place, but ranked stresses me out, and normal draft is what I normally play. I don't want to stomp my enemies over and over, just to later spend a day or two wading through fed enemy teams that win all lanes. I rarely feel like my input in a match is game-changing to the point where my decisions matter in determining the outcome of the game, win or loss. Is there a good solution to this issue?
