Guys... sry if I'm stupid and did not understand, but ...
Frenzied Regeneration: Instantly converts up to 60 Rage into up to (max((AP - 200% of AGI) * 200 / 100,25000% of STA / 100) * 1) health.
In my atual gear, my buffs and bear form, heals 25,492.
But, if a have vengeance, anothers buffs, agility trinkets and anothers thinks, the value is... 25,492... oO
This should not change the value based on Agiliy and AP?
Sry my really bad english, but if don't understand, I can try to be more clear =/
