And then holey cow, I have to agree with Melkhi here. It really seems that cow is now a beefed up version of what staff/shield was the past year. Better, including universal, mitigations paired with an ability to still perform while stunned (it even gets a serious damage boost while stunned) while also getting a boost in damage and no negatives (like the nerf to damage for bulwark). It all seems a bit much.
It seems more logical to me to not get the buff to stampede while stunned but maybe some extra oompf to moo and chew. And maybe some kind of a negative for cow, like with bulwark, would bring it more in line with other tank skills (maybe cows could only be able to eat certain types of food?)
Overall though, I think cow is now the new tanky outlier and probably could do with a bit of temperance in mitigation and damage numbers.
