New ranked system designed to keep solo players down

Well looking over my past seasons since season 2 i discovered that i have always been over 50% win percentage. When they introduced this new ranked system i have discovered now my win percentage has gone down a full 7%. This tells me that if you play solo you will have a major disadvantage to win games compared to the old systems.

Lets face it if you solo you have more variables that will make you loss.

-You either get duos that either are bad/troll -You face enemy team with comms and cordination while you do not. -Enemy team has more/all duos and your team does not.
