As a solo player I honestly don’t mind facing duos, but I wish I didn’t have to manually check this every game on a 3rd party site like porofessor. This has become a golden rule for me, so I don’t get surprised by unexpected / weird attention from enemy support or jungle.

They admit that it’s a slightly unfair advantage an even puts duos into higher mmr lobbies, but at least be transparent and indicate this to everyone in the game.
