Suggestions for fixing ranked play(solo queue)

So almost everybody has had gripes with solo-queue and riot has recently added some features to help fix some of the problems in the game ei. surrender without LP loss if an afk person is in the game before seven minutes. In my opinion there is still many problems still. Riot should add on to the DC or afk surrender to include if the team votes to surrender because lots times everyone is there but one or more players is blatantly a troll and loses lane or doesn't even play in his lane. Another issue with solo queue is LP gains and loss. LP loss is the main issue with the current ranking system. Since league is a team based game half your LP should come from your champion rank that game and the other half from the games outcome. I believe this is a much better system because solo queue should be more based on how you play rather than how a team of complete strangers cooperates. For the people that say you just need to carry harder, if your whole team is feeding no matter how much you try and help them, you just cannot do enough to win.
