I went from bronze 2 to emerald 3 this season, once I understood implemented good roaming and vision in my games. I went from blaming my teammates and not having a clue why I was losing, to feeling like the games are in my control.

For more context, I am an OTP Milio with a 56% WR across 200 games this season. https://u.gg/lol/profile/na1/milio is roaming-milio/overview

Before you suggest I just pick up another champ, I will not do that. I am looking for ways I can adapt my strategy and play-style to become a better player, regardless of champion.

I breezed through gold and plat but am having trouble in emerald. In this rank, it seems that the enemy supports also know how to roam, and they are having more success because (it appears) that their champ is better at roaming than Milio.

Most commonly it's either a tank/engage like Naut/Blitz/Maokai who performs successful ganks, or a roaming support like Janna, Bard, or Pyke, who are very good at denying vision and contesting/getting to objectives before I can.

This is the first real hurdle that I've run into on my journey so far, and if anyone has any insights into how I can remain effective against these better roamers, I am happy to hear it!
