Is there a reason that Greater Celestial Adornments Volume III is the ONLY trade skill recipe book that doesn't drop from TS quests?
Unfortunately that doesn't answer the question of why it is the ONLY tradeskill book that is excluded from the tradeskill quests reward table. We've got books from 3 expacs back.. and this one from the current expac is excluded. If it's a mistake, it would be nice to get it fixed. If it has been intentionally and explicitly excluded, I'd be interested in knowing why. The book is already heirloom.. which is odd enough.
I have never gotten any of the white adventuring adornment recipes. I still use PoP adorns because I can't make any from this expansion.
I and II drop from the TS quests very rarely, as do the orange VII recipes.. but for some reason the III recipe was excluded. There are only 2 recipes in the 'new' adventure white adornment books that are upgrades over the PoP adorns... The extra attack adorn (1 slot) and the crit bonus adorns. All of the others are 100% identical to the PoP white adorns, just using different mats. Which means you can get them from off the freebie armor... so there is no reason to make the 'new' ones since you can get identical ones for free.
There is also a Greater Celestial Adornments Volume IV. My guildmate just got one from the library PQ.
The only one I haven't gotten from the TS quests is III.... because, for some reason, it is excluded from that loot table
