Solo vs duo × Triple

Solo vs team full destruction

I’m a 2 finger player on my iphone 12, and I’m surely seeing more player are obviously 3-5 fingers players, so I am not sure if 2 finger can even climb further, but anyway I want to try. But there’s one problem, I don’t have fixed group, I’m always queuing with pubs, and 80% of the time there’s always one guy decided to roam on his own and never care about teaming. I’m so fed up and lose so many fight because it’s always 2v3. So I’m looking for tips to maximize my chance of winning more points in this situation.
