Prestige rank doesn't tell anything about your opponent, apart from how much time he spent playing costum/automatch games (1v1 to 4v4, even vs AI). I don't think Campaign is included. So I wouldn't take it as an idicator for how good a player is. I wish they would replace it with a proper ingame ranking system.
I love playing on winter maps, but I dislike deep snow, blizzards and cold tech. Sitting around campfires for 60 sec is not fun, and I have never seen a tactical use of blizzard in all of the games I played.
