If not, there should be a 4th specialization such as the guardian spec for druids, called Earthguard or something that uses either dual wield or 1hnd + shield or a staff, lots of room to theorycraft around that. Dual wield/staff could get a huge boost to armor to equate to a shield. And if you used a shield it would give you a boost to attack speed and attack power/damage dealt. Certain Glyphs can be removed and there can be some of the stuff from enhancement and elemental carried over to this new spec.
Glyphs could be something like;
Earthen Weapons : Each attack has a 100% chance to proc an ability similar to maelstrom weapon that works differently in that it can only be used for heals and each stack increases healing done and the duration of the heal by 30% each and is effected by mastery, 15 second cooldown between procs stacks up to 15 times and has a 3 minute duration every stack past 3 also leaves a heal over time for 2 seconds per stack for 20% of the base heal.
Improved Feral Spirits : Feral Spirits cooldown is reduced by 30 seconds and they heal for 20% more.
Stonewall : You gain 55% more stamina from items take a passive 10% less damage and gain 100% more threat.
Superior Edge : Attack Power scales into Block, Parry, and Dodge lightly by 1000 per .75%
Lifestone : Each attack has a chance to heal yourself for 1% of maximum health, cannot occur more than once every 2 seconds.
