This simple mod grabs your total, gross threat from the Threat-2.0 library(the engine behind Omen) and divides that number by the seconds spent in combat. Upon exiting combat, the result is dumped to your chat frame for you to see. Threat is total threat vs all known targets.

This requires you have Threat-2.0 installed. If you have Omen installed, you allready have Threat-2.0.
