One thing I've noticed is that there are no "Player <Guild Name>" display within the game. It might be because people can be in multiple guilds and it would either make this really messy or just not worthwhile to display.
Is there some way to simply make the player names glow differently if they happen to be in any of the guilds you might be a part of?
I know tabards exist, but no one wants to cover up their outfits. I feel like this game having so many choices that this is something pretty big that is missing. Maybe there is an add-on?
