My 2 ranked games today -TT topic
First game, I got auto-filled mid.
While I do the most dmg of both teams (16k to champs, 2nd is fed ennemy ADC with 11k dmg), and get a 0/1/0 KDA, my teams feeds all lanes (+ the jungler who was toxic all game long on top of it). Game ended 24 kills to 2 kills. http://matchhistory.oce.leagueoflegends.com/en/#match-details/OC1/174283397/200842675?tab=overview
Second game, I got my 2nd role, toplane. I play Renekton first pick against Riven, I go 2/0/0 with 1 solo kill and 1 1v2 kill. Meanwhile, our jungler give first blood cause of a "lag", and our mid get DC for about 10 minutes after giving some kills. Then our team surrender cause we were too far behind after those DC and lags.
I guess I lost because I lack of skill =D So the match-making system will adjust my MMR to lower level! Makes sense!
