When did this turn into Call of Duty?

Every single game I get in half of the players are 14 year olds who think theyre better than everyone else and even if they have 4 deaths in 6 minutes its someone else fault. On top of that literally every 2nd game is dodged because of fighting/bad picks etc. I stopped playing cod for a reason... Now I get the same shit on league.

There really needs to be some sort of age restriction on this game, Like do what Korea does, damn. It'll at least help with the issue of annoying 12 year olds in every game.
