I did my 10 placement matches and was placed in silver 4. I proceeded to log out and not play again till the next week and i played one as support and went something like 0/4/11 i think it was and then it placed me in Bronze 5. I was like wtf. This is outragous.
Placements the first time around were messed up and people were not placed according to their MMR, so they required everyone to play one more match and would place them where their MMR was. You got Bronze because your MMR was very low from last season, Silver 4 was too high due to a mistake by the system, sorry.
