Recommended DPS for this build to be effective for Act 3 MP0: 70-90k? your call (I started using it at 99k and it worked like a charm)
Basic gear requirements: 24% Movement speed, ≥27% XP gem, Hellfire Ring/s, Leoric’s Signet/s optional (the multiple rings are so you can equip one on your follower).
Advanced gear requirements: Legacy Nat’s (I don’t use), 1.04 Nat’s (I do use), or max discipline gear. You need to have either the discipline regen from Legacy Nat’s or a large discipline pool, 50+, to fuel your constant vaulting. I imagine the Nightstalker passive can be substituted if your crit chance is high enough.
For a hatred generator I use Cluster Grenades for the nice AOE (Strafe-Drifting Shadow is not good for taking out an entire mob of Skull Cleavers).
My hatred spender is, of course, Strafe runed with Drifting Shadow for the 100% movement speed.
My other active skills are: Bat Companion, SP-Gloom, Prep-Battle Scars, and Vault-Tumble.
My Passives are: Tactical Advantage, Vengeance, Archery (I dual wield; if you use a manticore and are short on discipline, this would be an excellent passive to switch out for Nightstalker).
As for play style, whenever I’m not in combat I’m either vaulting or running at +89% movement speed. If I see a lone Fallen in Areat Crater lvl 1, I just strafe him at +89% movement speed and never stop. When I come upon a large horde of demons, I hit SP, toss a few volleys of grenades, strafe in a circular pattern around the center of the horde to pick off the demons that had escaped the grenades and pick up health globes for the 20 hatred. Once all the monsters are dead, I vault away strafing small packs of 2-3 monsters as they present themselves. At 2.46 attacks per second, this is accomplished in a matter of seconds.
I have yet to calculate what my xp/hr is as I just started using this build yesterday; however, when I calculate the numbers I’ll post them here.
The most important aspect of this build is that it is just plain fun.
Edited to include the rune variation in some areas.
