Why is this even a thing?? It's a bad idea for so many reasons. First, it's just annoying, it clogs up your friends list with people you will likely never play with or talk to again. Secondly, it goes against best practices for player safety by removing a privacy filter and if you have a negative experience with a duels partner they can immediately slide into your DMs and harass you because you're their "friend" already. Please stop enabling this!! Related tangent: creating new teams with a random duel partner you only played with once is also very annoying for similar reasons. I get you want there to be a social element to the game but this is just too much.
