This is what I would do for BiS:
(Note: PE, not EB.)
http://www.wowhead.com/compare?items...436:96485&l=85
Helm: Headpiece of the Witch Doctor
Neck: Soul Prism of Lei-Shen
Shoulders: Shoulderwraps of the Witch Doctor
Cloak: Deadly Glare Cape
Chest: Chains of Counted Souls
Bracers: Vein-Cover Bracers
Gloves: Gloves of the Witch Doctor
Belt: Longdraw Chain Belt
Pants: Kilt of the Witch Doctor
Boots: World-Mote Sabatons
Ring1: Ra-den's Evolving Signet
Ring2: Ra-den's Summoning Band
Trinket1: Cha-Ye's Essence of Brilliance
Trinket2: Breath of the Hydra
Weapon: Athame of the Sanguine Ritual
Offhand: Tortos' Discarded Shell
Obviously there are alternatives for the Ra-den pieces. I skipped the heroic trash drops, since you can only get those from the BMA, and I also skipped the randomly itemized wrist, since it's very unlikely that you would get the technically BiS version in T-forged. There is an offhand that has better stats, but I refuse to take an OH over a shield. :P One really nice thing about this setup is that it skimps a lot on the spirit, so you're just barely over the hitcap and you won't need to reforge out of spirit much at all. In the event that the 4-piece isn't used on every fight, I would switch the helm out for the haste/mastery helm, leaving 3 pieces of tier still. I took that neck because the build is really skimped on spirit as it is, and I hate the idea of taking a pure mastery or pure crit piece. I will be open to switching to the crit neck, however, if crit begins simming really high for PE in the later part of the tier (once we get the meta, for example). The cloak is a tossup, as the Ra-den one is already thunderforged, but the itemization on the Durumu one is so fantastic that it could be worth it to hope for a thunderforged one of that.
