He should train in 8v8 before joining ranked soloQ.... I mean "RANKED" = you know what you are doing and you are serious. Not here to troll.
He was sad because he was bad and decided to ruin other people matches ? Nice attitude ! *slow clap*
8v8 says "training". He have to train here and get better I have nothing more to say. He just can't ruin ppl matches/promotes/rank just because he is too lazy to train and doesn't want to get better.
