Heroic Strike, however, has anywhere between 2 and 3 times the crit (and therefore effective Deep Wound proc) rate than Devastate.
Nice spreadsheet, though. Will be looking over it some more tomorrow. I have been getting Rawr.ProtWarr up to date recently as well and would like to see if our end results end up fairly similar. :)
Andenthal, while I agree that Heroic Strike is way too powerful right now, I'm not totally sure you are giving some of the other elements (especially Sword and Board) quite enough weight.
I'm also not sure why you are comparing Vengeance and Hit/Expertise. Hit and Expertise are multipliers on your current damage output. Therefore the effects should almost always be multiplicative. In fact, with higher levels of Vengeance one would suppose Hit and Expertise become more valuable than Strength, for instance, as Strength will be a small static increase compared to your much inflated Attack Power yet Hit and Expertise will still give you a percentage-based gain on your damage.
That all said, I have little doubt that Heroic Strike will end up being nerfed. It's too strong for all specs when compared to other abilities and has been all through beta.
