So for the moment we have rankings for WvW titles that other borderland enemies can see and that concept in itself is ok. Though, what would be nice is to be able to see ranking of fellow players on your server.
How I propose that idea is implemented is to instead of having a text tile, have a visual mark that indicates your ranking tier(bronze, silver etc). And I think using the ring you see around veteran and supervisor NPC around our actual name would look really awesome, so bronze ring for bronze rank, silver rind for silver rank and so on.
It would be nice to have this to show your dedication to wvw and bring fear to the enemy when they hover onto your name.
