Keeping enmity on a single mob is simple. Halone combo and flashes does the job.

Multiple mobs is a different story. I normally Savage blade one > Halone the next and voke the third. (obviously weaving flashes between)

The problem is when there's 3-4 mobs and the healer starts going batshit insane before I've managed to get threat on all of the mobs. You don't need to cast cure on me when I've lost less than 2% of my HP, I'll be ok. >.>
