Mists Gold-Making Speculation: The Fifth Element

There's a new crafting material coming in Mists, and it's even more useful than a multipass... believe it or not.

"Revered by craftsmen throughout Pandaria, this spirit is used in countless recipes."

Well, I wouldn't say countless, but it's still pretty darn useful. The item in question is the new Spirit of Harmony. The role this item has in crafting is like a cross between a Chaos Orb, a Volatile, and a Primal Might, so it's kind of a big deal. The total count for items crafted with this item is 145, and it's not just used in random junk... it's used for transmuting gems, the crafted PvP set (Contender's), leg enchants, and just about every level 90 crafted epic. The interesting thing about this item is that it drops off just random mobs at any level and that it's really, really rare. 

Wait a sec, that's not a Porcupine Steak...

If it hits live, this item has the potential to  become a pretty narrow bottle neck for crafting in the early day's following mists, especially with the transmutation of gems. I thought to myself that there had to be more to this. 
I did a quick search on Wowhead and it revealed that the Spirit of Harmony has a dark secret...


The following are data-mined, but unavailable in the beta: 
Spirit of Winter
Spirit of Autumn
Spirit of Spring
Spirit of Summer
Spirit of the Season (Which acts as any of the above)


Their uses, so far, are unknown, but it seems that maybe these items have a part in the smaller crafting jobs. I'm crossing my fingers for the transmutation of gems. Since crafting is very new to the Mists beta, I feel it's very likely that it's just not yet implemented. 


So what's the point? Well the only certainty of just about any Beta is that there will be uncertainty. Some items make the cut and others don't (Anyone else remember poor old Eternal Might?)
