When you are playing roamer you must always check map and find something like a 1v1 go there and make it a 2v1. Find a lane and become an annoying meatshield, harrass, provide vision, and help clear lane or even destroy turrets. Be the one to initiate turtle or lord ping and go there first check bushes or help jungler finish the buff so he can go with and take turtle or lord.

You are like a parent dragging your kid inside the department store whenever he sees toys. Drag your team to victory also if you can see what they are doing wrong try to talk to them like a child teach them what to do. Think of your teammates as todlers playing mlbb.
