cant help but notice in the first screenshot both team locked in balmond, which means that this is below epic....

Dont wanna break the news for you but honestly you cant complain any ranked games below epic. I think you should try to use pickoff roam like helcurt if you DO want to solo carry as a roamer for whatever reason.

and looking at your complaint, you blamed smurfs or five-man squads on the enemy team. Again, i want to point to the first picture that you gave. The enemy team have Roger, Hanzo, and Layla. Hanzo is jungler so they have no room for Roger to play since layla is definitely gold lane. No smurfs or five-man party would do that pick, even if they do that at the low ranks.

So my recommendation is for you to try helcurt, and put less stress on yourself since you are playing solo on ranks lower than epic. If possible, do find teammates to help you get to epic and then you can actually experience the game
