...so, Blizzard joked last Thursday that it would implement a special EPEEN function to limit player interactions with each other based on gear level, with a special, growing bar over a player's head that would signify their gear and coolness level.
The creator of TidyPlates:ThreatPlates took the idea and ran with it.
Yes, it's a real mod. If I wasn't trying to be quiet in my cubicle right now, I'd be lol'ing.
EDIT: It requires GearScore to be installed to run properly. It doesn't need to be enabled, but it does need to be installed. Bahh I had hoped to never "infect" my machine with GearScore, but if it's to make a mockery of it, I suppose I can forgive myself :)
