how do you think you deserve silver when you beat bronze 5, bronze 4 and unranked players?
you trashed your mmr and elo prior to the reset ... if you look at the image i provided it would show that... so how bad your mmr was... it takes a while to get it UP to gain rank. but when its in the dumpster... well
i understand your frustrations. im not discrediting it... but you werent playing silvers. or even high bronze players in your placements. that is why you got put where you did. if you continue you to do as well as you did in your placements you will climb fast. best of luck
p.s. rank dont mean anything... just have fun and enjoy the game
