How can I disable these horrible heads ?

How can I disable these horrible heads ? I can not concentrate on the game , it anger and infuriate me. Have you thought at all, as players will react to this update? League of Legends for me was a way to relax , but today I got a dose of huge stress. I believe that the graphic's update like this changes without the possibility of disabling them, just do not respect the players . Today, you have shown how important your players for you.
