Protector of Pack bugged

So I was running tests on this talent and got this results!

(well I can’t post the pictures here)

Its not storing 5% damage to extra heal in a regrowth, it’s way less.

(well I can’t post picutrs here)

I mean, feral heal is already sad at retail and our cap stone is bugged??

Were you testing on a training dummy that was at 1 HP? It doesn’t count overkill damage.

Yaa was on a dummy!!! Guess is that so!!! Ty
