Now that Beta is winding down and I've wrapped up my reviews and revisions on the recipes, this is a good time to take a look at the various factions in MoP. There seems to be a distinct change in the accessibility of faction-based recipes that should make life a bit easier in Pandaria.
I don't know how many of you have analyzed the recipe lists on Crafter's Tome (if not, why not?) but most professions have only one faction to deal with. This is especially true of "gear" professions - those of us who'll be making armor. I've compiled a brief chart here to highlight this:
Blacksmiths: Honored reputation with the Klaxxi
Enchanters: Revered reputation with the Shado-pan and the August Celestials
Jewelcrafters: Honored/Revered/Exalted with the Order of the Cloud Serpent
Leatherworkers: Honored with the Golden Lotus
Tailors: Honored with the Golden Lotus | Exalted with the August Celestials
You can see that Blacksmiths, Jewelcrafters and Leatherworkers have a single faction which holds recipes for them. Tailoring has a second faction, but that can be skipped if you don't care about making the new uber-bags. The vast majority of these new recipes can be unlocked by grinding one faction and you only need to reach Honored with that group.
One major exception is Enchanting - you'll need to work on two groups and you have to get to Revered with each group. However, the recipes are divided by type. If you want to focus on weapon enchants, you start with the Shado-pan. For those who'd prefer to get the bracer enchants, you can go with the August Celestials. This at least gives you the ability to prioritize the types of recipes you want.
The other major exception for faction recipes is Jewelcrafting. Instead of simply going to Honored, Jewelcrafters have new recipes at each of the top three reputation levels. I think the main reason for this is that the goodies they're unlocking are seriously awesome and entirely optional. So you Jewelcrafters out there are going to have to work a bit harder to get these recipes. They are the ones that make the new panther mounts. The final recipe at Exalted is the Jeweled Onyx Panther. For those who don't care to tackle the massive grind, you can stop at Honored and pick up just the first two. Or you can go for Revered and have all four colors. If you want to make the top of the line panther, you have to reach Exalted.
A minor exception to the new face of faction grinding is the MoP Tailoring bag. They put this on a different faction from the gear and they made it also an Exalted level item. I think we can assume from this that they want access to this bag to be pretty well gated. Again, these bags aren't really required for any player. I think it's reasonable to make the pattern harder to get.
In general, I appreciate that they put in a lower bar for the gear recipes. Players greatly rely on crafted items to progress through heroics and early raids, so it shouldn't require days and days of faction grinding to access those recipes. And I feel that the recipes which do demand a higher grind are those which are fun/convenience items and will not interfere with character progression.
Feel free to leave your thoughts in the Comments! If you have a question I can try to answer it, but the Beta realms will be coming down any time now and I might not be able to dig up an answer for you :)
