What can actually be done about trolls?
/Rant Begin
So ranked is ending soon and with one account already getting that victorious skin, I decided to get the other to Gold. I get into a game as Vayne vs. Karma and MF bot. It's hell. First 7 mins I get poked down (expected) and I gladly give first turret. I keep farming cos I know I'll turn into a lategame god. Then next thing I hear is "An Enemy is on a killing spree" and guess who it was, Yasuo. I know it would be hard but didn't flame TF or anything. Just kept farming. Next thing TF says, "You know this game is lost right, that's why I'm feeding". This was around 20 mins. I already had my Phantom Dancer, Stattik and BoTRK. I was like wtf. Next thing dude sells everything and for the next 30 mins he kept buying all cloth armor, all doran's shield, forbidden idol and all that. Meanwhile I and my other teammates were working together. I got killed a lot cos of the focus on me. Didn't matter, we kept going and I kept encouraging them telling them never to surrender. We eventually aced then and got one nexus turret. Still the TF didn't think "Oh we can actually do this". Nope. He kept feeding until they were all full build and MF and Yas Had GA. We tried and tried but in the end we lost. I spent 59 mins of my life with a troll who thought the game was lost from min 20. I lost the game because someone couldn't man up and try to play better. I told him "I hope you get banned" and his reply was "Idc. Will just make a new account". I was tilted beyond measure. Now my question is, Dear Riot, since you are in the mood of granting wishes, can you help come up with a solution for trolls?
