Helpz?

Well after reset i got placed in Bronze V. Well in a few days i went straight to Bronze I. Now every game i get in well to be honest 60% of my games i have either a AFK or a Troll. So now im back to Bronze IV from Bronze I. Im trying to get back to silver, so i really could care less of how good you are, just as long as you dont AFK or Troll then im fine.
