TidyPlates:ThreatPlates suicidalkatt

Theme for TidyPlates, you must have that installed for this mod to work. ThreatPlates allow you to quickly see if you have aggro. They can be configured for dps/healing or for tanking. I use them for tanking on Vranx and I think they are great. In tanking mode the plates turn green and get smaller if I have aggro on the mob, and they turn red and get larger if I lose aggro. This makes it easy to click on a nameplate to taunt a mob back to me.
