yes pls
Specifically in chat instead of the S or D used to show a player's main main it could show O for players whos highest rank is their overall one so that u know whats up. This change would probably not require anything other than the chat prefix shown to be modified but might encourage players to be more mindful of other classes so that we can maybe avoid so many maps being designed for demo and 100% wallpogo for soldier or designed for soldier and all triple pre magic for demo.
Since the overall rank would only be smaller than your best class rank in fairly unusual cases it should probably take precedence over a class rank if your overall and class rank are the same, but i'm not so sure about this. Maybe it could be a niche user option?
