Feeders, trolls, and afks

Can you please bring back loss preventers. Im in bronze and half the games i play are trolls, afks, or "hyperfeeding." I think that since you are able to tell what position people are playing, make it so that in ranked if someone feeds a LOT the other members of the team get a loss prevented. Also if someone is building troll or picks a troll champ just give people loss prevented. If someone is afk for over half the game it should be a loss prevented for all but the afk. Its insanely hard to climb when you get afks and trolls in most games. My last game as singed was lost because a has stacked tears and intentionally fed. I think you should give back lp if someone is condemned by the tribunal for these stupid acts. I know this is difficult to balance and prevent from exploit ion, but i miss the days where all games were loss preventeds. Sorry for any spelling mistakes
