I will say no just like your twitch thread.
I would rather relic focus on other things like mod tools/balance/maps than spending dev time on stuff that doesn't actually impact the game.
You understand that dev's are broken into different disciplines and that dev's working on creating faceplates linked to rank would have no impact on dev's working on map balance, game balance etc.
A quick and simple way to do this would be add a faceplate which has space to display ladder rank.
I am guessing, 1 GUI artist, 1 GUI programmer. 1 week of work.
