And if you do choose preferred three maps you'd like to play, there would be a notification that it may result in increased queue times - and that you might still sometimes get maps out of your list.

Personally, I don't care for Fracture and Split in the current rotation and would enjoy the game more if I could favor, say, Pearl, Lotus and Ascent in my solo-queue matchmaking. (This setting would probably have to be for solo q only).
