The health you sacrifice is not that much compared to the extra damage your opponent takes. So no, Berserk doesn't fit that description, especially because it ignores defense.

Imo, Rock fits your description more. The Crit damage reduction is nice. But by itself, Rock may put you in trouble if you get hit by combos that normally would be screwed by Critical triggering at the wrong time, like Kenjutsu, Supremacy and Leash. Rock, however, works wonder when used in conjunction with the unbreakable attacks. When Rock activates during the interval, you won't fall and still continue your attack. Add in Revenge and the aforementioned Berserk for even more damage.
