this is a very hard problem to solve but we have some ideas. any solution is more long term, though. possibly OW2 or later. sorry i know that’s not the answer you wanted but it’s actually very complicated with the way consoles work and the rules regarding account creation.

Someone being better than you is also allowed, they will rank up.
Someone being better than you because they’re playing in a rank far below their regular rank is not allowed, as that gives them an unfair advantage, and according to Blizzard anything that gives an unfair advantage is cheating.
