Rank Base Mastery Flairs? Upvote if you want to rep your rank.

So since the addition of the team icon flairs for the world championship, I've had this idea that why not make mastery flairs for rank. It would be cool for players to show off there rank at all levels and would be another way to reward players for what there rank is other than end of the season rewards. Do you agree?? Or what could make that idea even better ?? Upvote and comment to spread the idea.
