Orcs of the Red Blade

Hello! Seeing we've had a bit of fun lately with that Alliance guy in Terokkar, I thought it would be nice if I told about this AddOn: Spy

http://www.curse.com/addons/wow/spy

Whenever a nearby character of the opposite faction gets close, he's going to show up on the Spy interface, and try to determine class and level based on what ability was used.

To add on it, if a stealther is nearby, you'll get a blue bar on top of your screen with name, class and level of the stealther from the two second he might've been visible.
