I have no HK weapons and parsed 2800 on Murdantix and parsed 3200 on Sicaron (But I was a little out of it by then and forgot to buff alot of the time) so I'll give a more accurate parse on Sicaron next week.

The spec is really easy, but with ANY lag or no fervor (FERVOR, not Living Energy)+ tablet you should be using blazing Strike on 4 CP NOT 5 CP. With the murdantix parse the only time I went to five CP was when it used a 2CP power to get from 3-5. Make sure you keep fiery spike up it's where a lot of your damage comes from. Well alot considering that it's free.

I do not use expose weakness and still find that unless fervor and tablet is up I am still not hitting evert GCD.

Remember NB has some kick ass defensive CD's You have Twilight Shelter and Twilight Transcendence. One gives you 80% Damage Reduction and one basically heals you a shitload and gives you 50% Damage Reduction. Remember, you don't DPS when you're dead.

Opener is Conceal (Stealth) >Dark Malady > Builder Macro >Scourge of Darkness > Fiery Spike > Ebon Fury Macro Spam.
Regular Rotation is: Builder Macro and Finisher Macro... If for some reason Fiery Spoke is going to drop, apply it manually.

AOE: AoE Button > Finisher > Keep Fiery Spike on main target.

Like I said, this build is easy, and straight forward, no confusing Impale, 3xFB, one this, make sure you blink. And you don't blink into a tail swipe 😛
