Hello misters and ladies! I am a normal silver player, that never went past Silver 1 at all. This is my profile: https://euw.op.gg/summoner/userName=abocanhadora I manly play support in ranked games, eventually jungler if its needed. I am, for the 6th time, on my promotions from S3 to S2. Like the last 4 tries, I have a free win, which means I only have to win 1 from the next 2 games. Any hints, comments, help you may want to give me...? Anything would be apreciate, since I am really that desesperate -.-'
