There isn't a whole lot for Ferals from either faction, the shoulder enchants are about equal. The biggest difference now is with the SSO exalted neck pieces.
The tanking one has 48 Stam, 13 hit rating, and 18 expertise rating.
Aldor proc: 100 dodge rating
Scryer proc: 100 expertise rating
Feral usually need defense on their neck, but if you don't, this is good. I'd probably want the dodge rating proc. Between that, the commendation of Kael, and Badge of Tenacity, I can probably hit over 70% dodge for a few seconds. I haven't had a problem yet generating threat, so I don't really need the expertise. Although the ghost haste buff mobs get when their attacks are parried does hurt.
Melee DPS neck has 19 Stam, 18 Agi, and 64 AP.
Aldor proc: 200 AP for 10 sec.
Scryer proc: 500 damage melee hit that can crit.
Since the 500 damage is arcane, I think it ignores armor. If that's the case, 200 AP adds around 35-40 DPS with my feral stats, raid buffed. That works out to around 350-400 damage over 10 sec. Scryer buff seems better for DPS.
