So far from my experience playing tournament. I believe you play against people within a certain leaderboard position. It feels as if I’m playing in a Diamond ranked lobby every time i play it. In my last game I was playing against UI226 (whatever his username is) and hes basically in the top 10 of the leader board position and we got slapped. My team mate was in top 25 and I’m in top 4000. I think this is what is meant by “competitive” in the world tour game mode.
You you’re probably right. I sure hope they have a skill based matchmaking system in place or plan on adding because without it, it’s not fun for anyone.
