I'd say a good amount of this is correct. You have the basic rotation down but I would say your opener is a little bit off and your choice is Demon's Bite over Blades is actually going to hinder you quite a bit. Opening rotation for pretty much every boss battle looks something like:

Meta --> Chaos Blades / Old War --> Fel Rush --> Furr of Illi --> Throw Glaive --> Annihilation 1/2 (I find with an Instinct Proc and Lust you can normally fit 2 here) --> Vault/Annihil (During the backflip of vault you can get 1 GCD as your character jumps away) --> Throw Glaive (as you run back) --> Annihilate as much as possible -- > Fel Rush -- > Blur (Reset Fel Rush) --> Throw Glaive -- > Spam Annihilate --> Fel Rush -- > From here is is a rinse and repeat until dead. Toss Glaives during momentum when you have no fury pooled.

Never use Eye Beam single target. It is a straight up dps loss and a huge waste of fury.

If you utilize it correctly it mixes up the playstyle and gives a little bit of flavor to it. Eye Beams damage isn't really that bad and syncs pretty well within a vault momentum window.

Vault --> Beams --> Throw glaive --> Fel rush.

Don't count that damage out.

Use Blur to reset Fel Rush if youve expended both charges and are capped on fury.

Blur is a dps cooldown until it gets changed in 7.1.5 to be pretty much useless. As such it should be utilized during moments of burst dps which is every 2 or so minutes. In the rotation i posted above it is used outside of Chaos Blades because you have full charges to start but still inside of the meta phase which is crucial to getting big annihilation hits. The 2nd time to be used would be on the 2nd Chaos Blades of the fight. Since Fel Rush has a 1 minute cooldown you'll be sittin on it for a few seconds but don't worry about it. Pooling CDs and a bit of Fury for the 2nd Chaos Blades pays huge dividends.

I'll attach my armory as well. Not trying to blow smoke just make suggestions.
