Copied from my other post:

You didn't add Carve and Spit, which is your most powerful ability.

Your lack of a proper 60 opener is depressing --

You open with Salted Earth > Unmend > Plunge. That's simply inefficient.

For one, you are not able to keep the boss where it should be by opening with Unmend. By opening with Salted Earth "in front of them", you also lose ticks.

My strongest opener right now is as follows*:

Plunge > Scourge > Dark Arts > Hard Slash > Carve and Spit > Syphon Strike > Dark Arts > Soul Eater > Salted Earth.

This is insane DPS and threat, and beyond this point I haven't 100% decided on the order of which I'm using my other off GCDs.

I usually follow up with Hard Slash > Low Blow > Spinning Slash > Dark Passenger > Power Slash and this cements threat for the rest of the fight. But your opener is not only inefficient, it's trying too hard to do the Unmend > Plunge "combo" when the animations do not allow it.
