As stats on tailored cloth sets ricochet between the developers, the PTR and tailors buzzing like angry bees at the prospect of changes, healing clothies continue to click through their cooldowns to create two of the best healing sets in the game: the Primal Mooncloth set and the Whitemend Wisdom set. Primal mooncloth tailoring is where it's at for healers -- and it offers some tasty treats for PvP casters as well as anyone who wants more bag space.

Just how good are the healing sets? Most priests swear by their phenomenal +healing, mp5 and set bonuses, considering them clearly superior to Tier 4 and rivaling Tier 5. Patch 2.1 will buff the Primal Mooncloth set's overall stats and ease the component requirements. As a package, the Primal Mooncloth/Whitemend combo is weak on stamina (and some say the two sets don't complement one another as well as they could), but most healers compensate with other pieces, swap in stamina gear for specific fights or rely on enchants and gems to reach their preferred stats balance.

There's been some QQing over the fact that primal mooncloth gear is BoP and the complementary Whitemend Wisdom set requires the wearer to have a 350 tailoring skill to get the set bonus. Some players say these restrictions make tailoring "required" for cloth healers. Still, most priests feel the primal mooncloth's set bonus -- 5% mana regeneration during casting -- takes the sting out of upgrading away from their beloved Transcendence three-piece set bonus.

But before we /moon you with the details of mooncloth tailoring, what if you're not the healing type? PvP casters might be tempted by the Unyielding Girdle or the Resolute Cape (buffed to 349 armor in 2.1). And just about everyone craves more bag space. The 20-slot Primal Mooncloth Bag delivers, for a mere 72 Netherweave Cloth, 8 Arcane Dust, 40 Motes of Life (4 Primal Life), 40 Motes of Water (4 Primal Water) and 4 Netherweb Spider Silk from a mooncloth-specced tailor. (Well, what else were you gonna do with all that extra gold and farming time?)
