What are your plans for the crafted epics in Warlords? They seem to have made it difficult to craft the fully upgraded ones in time for raids opening.
Each epic requires:
450 profession cooldown items (BoP, needs 100 for base item, 150 for 1st upgrade, 200 for 2nd upgrade)
30 Savage Blood from Barn (BoE)
60-80 Sorcerous Elements (BoE)
For the BoP profession cooldown items you can craft:
4 per day from profession cooldown increasing with skill. 10 per day at 700 skill
6 per day from work orders. 12 with a lvl 100 follower
1 per 10 Primal Spirits farmed. ??? per day
You'll probably average 10 per day early on, increasing to ~17+ as you get a few skill points and a lvl 100 follower. Overall you can get about 300 in time for Highmaul opening without considering Primal Spirits. That means you need divide the crafting among multiple characters or do a crap load of grinding for Spirits. You could divide crafting like this:
Characters 1-3 make a tier2 upgrade and tier1 upgrade each (350 BoP items per character)
Character 4 makes 3 base epics (300 BoP items)
Supplement with Primal Spirits if you can't get to 350 items on any given character. Alternatively use 5 characters and you won't need Spirits. If you craft items from multiple professions, you can have one character count as two for crafting purposes.
That'll get you one raiding character outfitted with 3 items. Note that lvl 92 crafting alts won't have access to lvl 100 followers, and will have less output.
Savage Blood requires Primal Spirits or a lvl 3 barn, which requires 125 Barn work orders to build. The achievement is account bound (for now) so you can get the lvl 3 barn achievement very quickly by using low level alts with barns. Sorcerous elements are created through garrison work orders and profession cooldowns, and can be bought from the AH as well.
Are you going to have your raiders level multiple crafting alts, pay heavily for outside crafting, or maybe just not bother at all?
EDIT: In a recent patch it has become possible to buy extra BoP items with 10 Primal Spirits each. Primal Spirits can be found through gathering and killing mobs. It remains to be seen how much extra it is realistically possible to get from spirits. Also cloaks are intended to be included in the 3 limit, so you can only use 3 crafted items instead of 4. Things are still changing in the beta, so this information may not be accurate at launch.
