Friends request feature for BG

Hey,

Sometimes you have interesting game and you would like to exchange some thoughts about it with your opponent so maybe it would be nice to have a friends request feature for BG?
It could be for last played opponent or anyone who was in your lobby.

I was just thinking about this, the recently played list could easily support a tag for “Recent Duos Partner.” User story: when I have completed a BG Duos match, I want to quickly find my partner to chat about the amazing thing that happened in the match. Today, I cannot easily find who was my partner unless I remember their name, this makes me sad. You can either delight or disappoint your users…choose wisely. Thanks from your friendly neighborhood product manager.

It would probably be used for insulting and toxic purposes…
For example, I have only searched that list of their names to complain about their bad plays, like a guy that really tilted me recently by selling a very crucial and fat minion that i passed to him and he still do it despite i was making signs that i needed it back…
