SoloQ RNG

Playing solo Q everyday seems like im throwing dices already and game decided by who int the most, enemy get a bad team i win no matter what i do, i get a bad team i lose no matter what i do and im up and down on rank all the time, depends on how lucky or unlucky i get with teams from Diamond to Gold, i can be anything next days, i just dropped now from D2 to plat4 in few days and also watching few streams on Twitch i see alot of people circle between challenger and diamond. So yeah game is decided by who have better team and not by whos a better player(and yet we cant even have Voice Chat), its that really best way to rank everyone based on their team performance and not by their "soloQ" performance, that some1 can get -20 on a game he played very good and have S rank(playing vs fed enemy make it look even better) while some1 who played bad +20 with B rank its absurd for me. In the end this is not Team Rankings , its soloQ rankings and its fair to rank everyone based on their performance on each game to determine more accurate everyones deserved rank and to have much more balanced games and not what we have atm 1 sided games and very different skill gaps playing vs eachothers. I think we really need Voice chat if they gona keep this soloQ RNG and make games cariable even if ur team ints, either we need a different ranking system that give u -/+ rank points based on how u played that game +/- rank points if u win/lose, while they can also keep this old system with a different rank ladder and have 2 Ladders one that show ur performace with team and other ur solo performance. Heres my last games while im dealing most dmg as a tank (semi), destroying enemy jungler, warding enemy jungle all the time to give my lanes info where he will gank and having pretty decent macro plays. but i feel powerless if i have an unlucky team and my team inting withtout enemy jungle proximity. Thanks for reading and sorry for my bad english. https://imgur.com/a/mDd3T4J , https://imgur.com/a/nWpQvEg
