IF U CANT BEAT'EM????

So guys I'm a bronze pro :) in the sense that ive played a lot of bronze games. gotta simple question HOW DO YOU CARRY IN 3v3 **BRONZE **ELO? is there some sort of secret pick that doesn't rely on teammates?

it may seem rather silly question but ive played so many bronze games and all i ever get to is B2 when I get there I keep loosing no matter how hard I try some people don't bann anything some go AFK some ragequitt others int not to mention the all ap comps

plzz give me a concrete strategy for 3v3 ranked otherwise I only have this one: if u cant beat'em stay in bronze :(
