Can people stop using support comp in 3s ranked

The 3s ranked support comp in ranked is broken... especially if your playing solo and your team doesn't know how to fight against them. I know how to play against them, but when your teammates don't it can just fuck the whole game over. I hate hearing them say its my fault we lost, when im literally against two people in my lane solo, its not like I can 1v2 them a lvl 1...Overall its not fair if your playing solo and you have to go against support comps in a 3v3... As for the people who say just play in duos your self.... no I like playing solo in 3s.
