They went 1/11 and ruined the game.
Simply no idea how to play.
Please, please Riot ..... will you accept the fact that these new players are gonna get slaughtered in ranked, and put them in matches at much much lower ELO.
I suggest low to mid Bronze is a good starting place, no disrespect to new players. I was Bronze when I started ranked, and I deserved to be there.
The middle ELO bracket is way too polluted with bad assignments of players to this ELO space. This issue needs addressing.
