For jorde clothies, this can be achieved by either GSoJ and a 2 hit wand, or Ring+Wand+Boots. If you opt for the GSoJ route (with Garrosh's Pardon and Corpse Rompers), you gain 6 STA, 7 resil, and 9 armor. If you choose to go with Dignified Headmaster's Charge (with Boots of Unturned Loyalty and Lavishly Jeweled Ring) you gain 3 INT and 6 crit.

For leather, the BoAs provide ample hit. For hunters/enhance, go with Hogger's Trousers + (Band of Precision/Stillwater Dagger/BoA Leather Shoulders).
For Hpals, use Lavishly Jeweled Ring + Acquisition Bracers + Boots of the Unturned Loyalty.
For Rets/Wars, use the Bracers of the Most Trusted + Demon Band + Leather BoA (iffy about this, maybe other Rets and Wars can add here)
