Since the 1.7 patch, they enabled warrior's to be able to have recklessness, retallation, and shield wall stay through stance chanes, and because of this, they screwed up and all abilities will do the same.
With that being said, the whirlwind exploit is to have sweeping strikes up and switch to beserk, hit whirlwind and hit 4 mob's twice, easily doing 6000+ dps if you have recklessness up which is just sickening.
