Addon Idea: AbandonThreat

Lately, tanking with Radish, I've been using Omen to figure out when it's time to move on to the next mob in a pack (or who needs my Vigilance).

It's pretty wild, the difference between the threat I generate and the average threat generated by a DPSer. Some of it is because I'm always getting grouped with poor DPS. But halfway through most bossfights, I've got so much threat on the boss, there's no way anybody is getting it back. By the time they did enough damage to peel the boss from me, he'd be dead. At least if the numbers in Omen and the HP numbers on the boss are comparable, that's true.

This is an especially useful threshold to know for warrior tanking of add packs. Because my AoE threat move (thunder clap) is on a cooldown, I'm not able to really spam AoE threat on everybody. I need to rotate through targets and use Devastate, Revenge, and Shield Slam to build threat one at a time. Cleave helps a lot too, but that's on the swing timer so it's not strictly spammable. So, what I'd like is an addon that looks at the HP remaining on a mob as well as the relative levels of threat on the mob and does a worst-case scenario (assuming nobody has any threat reduction) and tells me if I've got so much, I should just move on.
