Tips on overcoming trolls, afks, people who intentionally feed, and people who lose lane then flame?

Like the title says these past few days not playing in a pre-made 5 group has been hell on earth. Yeah I could do the usual "report and move on" shtick but this is becoming a semi-chronic problem. It's always one player who for instance loses lane then goes on tilt, calls out the jg for not ganking him/her three times even they've been ganked once by the enemy jg, then our jg turns into a keyboard warrior who's not paying attention to any objectives and the game snowballs into hell. I always tell em just mute em and ignore em but there's always the people who have to prove they're right and just HAVE to have the last word. I can't just play Darius or Syndra and carry a 3v5 so please refrain from the "pick hyper carries" suggestion.
