Don't Allow Noobs into Ranked.

I started doing Ranked recently and I am quite disappointed to find that anybody at all can join ranked pvp matches this is totally unfair and just dumb. I seen somebody the other day in my 4v4 match on my team who just obtained the "look who's coming to dinner I" achievement like seriously?? it was the guys first time ever pvping and he gets to join my ranked match needless to say we lost the match thanks to him but more importantly thanks to the system that has no noob prevention system. If you have not played at least 50,100, ect normal pvp games you should not be able to do ranked matches or some other type of way to keep people who are not good at pvp out of ranked matches or just keep the people who have never pvped before out of ranked.
