Spec Annihilation with 2/2 Subjugation (for a 6-second Disruption).
Between your Disruption, any distance Charge, Force Choke and Intimidating Roar you have numerous tools to interrupt.
Stack your Fury while interrupting the casts (save your force choke) > Deadly Saber > Battering Assault > Annihilate > Rupture (now you have stacked all your dots) > Berserk (Dots now crit) > Force Choke (He is now immobilized while a large chunk of his health whittles away).....
After this he should be under 50% and in panic mode, this is the time to toss out a Deadly Throw for the healing debuff and finish him while interrupting with Disruptions, Charges and that Intimidating roar you've been saving up.
Finish him, moonwalk the hell out of there.
