a second wind nerf IS a d stance nerf. second wind is a large part of what allows warriors to camp out in def stance with no rage issues. both need to be reduced.
you shouldn't be able to sit there with a perma-barkskin with no significant damage output cost, none of the other tank capable hybrids can, why are warriors special.
def stance should remain a strong tool for a warrior under pressure, but he should be dealing reduced damage while in it.
