Bronze supports/thinly disguised carries
As I make my way from Bronze 5 again (currently dropped to Bronze 3 recently from Bronze 2), I am experiencing more and more Supports (mostly autofills) who play champs that are not meant to support. They often say they will (if anything at all), but then quickly announce they will go ap, do not buy ward stones, nor do anything remotely support-like. When they pick a champ like Annie, MF, Brand or some other carry oriented champ, I always mention that they are denying the team a support champ that will be needed. They promise that they will carry and don't seem to understand, or even care, that this can cause the team problems throughout the game. Does anyone have any suggestions on how to convince them that they are hurting their chances to win?
