Tank Vengeance, Resolve, and PvP

The changes to tanking made in Mists of Pandaria turned out quite well, overall. But there were a few rough parts that we're going to smooth over. The biggest one is the offensive capabilities of Vengeance. We like that tanks can provide meaningful DPS to their group, however, it swung wildly based on the fight, even surpassing the dedicated damage dealers occasionally. To solve this, we're going to remove the offensive value of Vengeance, but preserve the defensive value, by making it increase the effect of your active mitigation buttons, instead of Attack Power.

    General
        Vengeance has been removed and replaced with a new passive ability, Resolve.
            Resolve: Increases euwowgold your healing and absorption done to yourself, based on Stamina and damage taken (before avoidance and mitigation) in the last 10 seconds.

Then, to keep tank DPS meaningful, we'll be raising their damage, since it would be meager with no Vengeance Attack Power (Vengeance accounted for 70-90% of a tank's damage on high-tank-damage fights in Mists). To do that, we're increasing the damage of several prominent tank abilities. For plate-wearing Tank specializations, Riposte has been redesigned to convert Critical Strike into Parry, a defensive stat. That also helps keep secondary stats balanced in offensive value for them.

    General
        All tanking stances and similar effects now increases threat generated by 900% (up from 600%).
        Riposte is a passive ability for Blood Death Knights, Protection Paladins, and Protection warriors.
            Riposte now gives the character Parry equal to their Critical Strike bonus from gear.
