Asura Strike Stalker!
No, I'm serious. Right Jae? ;P
Its the perfect runner-class build. You run around and collect zen and fury on ifrit rings (while having asura strike copied), then boom! Asura Strike the stripped nigga. If they can't be stripped, do what stalkers do best: Run, and run until fcp dies out. Stalker may not have the best damage and HP modifier, but they win on one thing. Survivability.
