It's still worth using. If you think that 10% parry is worth keeping your stacks, you're absolutely wrong. Using SC does build awesome AoE enmity as well as doing pretty good damage WITH FUCKING 0 TP COST. Plus it scales so good with Berserk + Bloodbath for self-heals that 10% more parry rate is complete garbage in comparison.

Don't forget that parry rate is still parry rate. It's RNG. And it's only +10%.
