I decided to tackle Enchanting this weekend, since they were still tinkering with gear professions in Friday's Beta patch. The recipes for Enchanting have been static for a while now, so hopefully there aren't plans to fiddle with them again. That said, I found it ridiculously easy to level. Because of that, I wouldn't be surprised to see changes made. I have another toon who can run the process again if that happens.
On the Beta realm none of my Cataclysm recipes are orange on my Enchanter. The cheapest Cata recipe that's yellow in the Beta is Boots - Mastery. I'm not sure I would bother with this since it could be difficult to offload the enchanted scrolls when you're done. In my test of this recipe, I had to make 11 scrolls to get 5 skill points from it (at which point the recipe turned green) I think that's a pretty expensive proposition, but if you're trying for a Realm First it may be worth it to you.
For the purposes of evaluating the total "cost" of each enchant versus the other recipes in the same range, I used the values that Blizzard has so kindly provided with the new conversion recipes. In my calculations I used the following equivalencies to weight recipes against each other:
1 ethereal shard = 5 mysterious essence = 25 spirit dust
I realize that some of you may not agree with these values. But in the early MoP days this conversion may be the only way to reliably get these materials, so I'm going with it for the leveling guide.
Using the conversion rates above, I ranked all of the Zen recipes to find the least expensive ones. For recipes that grant multiple skill points I divided the total mat value by the number of skill points to assess a mats per skill point number. I used that number to weight each recipe. That said I'm still providing multiple options at each level so you can diversify if you choose.
Recommended Enchanting Progression:
525-551: Boots - Greater Precision (Bracer - Major Dodge | Cloak - Superior Intellect)
551-557: Ring Enchants for 3 skill points each (INT | STR | STAM | AGI)
557-575: Chest - Superior Stamina | Gloves - Superior Expertise
575-600: Chest - Glorious Stats | Gloves - Superior Mastery | Offhand - Major Intellect
For the first set of recipes, the mats are so close that you won't go wrong with any of the choices. They are literally 1/10th of a dust apart in mat value, not enough to quibble over to my mind. On the second set of recipes I fear we may be in for a shake-up. The ring enchants are drastically cheaper than any other recipe in this list, and yet they give you 3 skill points apiece. You basically get a skill point for 2/3rds of a spirit dust, which is unbelievably low. Even if you only got 1 skill point for a ring recipe it would still be the cheapest recipe in the whole list. So don't be shocked if this one changes. In that case, just start the 557-575 recipes at 551.
With the final wave of recipes we have three choices that are once again very close. These three recipes are about 1/3rd of 1 dust different from each other.This is another spot where I feel that some diversity could be beneficial when it comes time to sell your wares. The last set of recipes will remain orange all the way to 600 skill, so no gotchas in the skill progression at this time.
The total mats needed to go from 525 to 600 Enchanting:
66-68 spirit dust
34-36 mysterious essence
Don't forget that you can convert from one to another if your stash of mats is skewed!
If you want more details on the Zen Enchanting recipes, I've just added them to Crafter's Tome. Make sure you select "Mists of Pandaria" from the Expansion filter to view just the new recipes.
