de afk problem

Hello riot I'm currently frustrated because I had an afk in my ranked game. But sure not big deal , except if there is one ( or more) of them in every game which is exactly what happens. I got from 100 to 0 lp in 3 days with a total of 6 afks what are you doing about the ragequiters and the trolls riot ? what else form just telling us to report them? I'm sure as heck people would prefer a change of that nature instead of masteries and runes. Thank you for reading .
