[tough question] if you answer these 3 questions climbing for me would be easy

How do you 1v9 when your team is powerfeeding enemies and it totaly useless?

How do you raise your team's brain cell count?

Is there a solution to stopping or dealing with constantly getting 1 to 4 useless/feeding/bad teammates?

I'd really like some help games I play don't go well always because of team's literal skill they could easily be destroyed by a team full of Bronze Teemo mains (nothing against teemo mains or bronze players) it is absurd how badly some of my games go...
