BiS depends on which pet build you are running (as some people are playing fire or poison atm) but usually it is Physical though so...
Mask of Jeram
Tasker & Theo (trifecta)
Stone of Jordan (30% elite damage, 8% crit, 20% physical)
Royal Ring of Grandeur (trifecta)
3x Zuni (boots, chest, mojo)
2x Aughild (braces with 20% phys, shoulders with +15% FA dmg)
Witching Hour waist
Hexing Pants or Mr Yan
Any amulet with 10% CC, 100% CHD and 20% phys
Weapon either 2400+ dps Doombringer with 20% physical or 2200+ SMK (but you lose the +phys damage bonus) or 2400+ rhen'ho Flayer with addling toads as main spam (for rofllolEZmode in any torment)
That list is pretty much how I am running my phys WD with 2.7m elemental dps
as for
tall mans finger ring at T6 I would never drop SoJ for it tbh (espesh as mine is perfect

) but upto T5 TMF is fun
Armor stats:
