I arrived home on Saturday to discover that we had Patch Notes out for 2.2 -- and here I had no idea we had a new patch on the horizon! I've been working over the weekend to locate all the changed items and update my database, but I haven't completed the review yet. I didn't want to leave you guys in suspense though, so I thought I'd post my initial observations.
The bulk of the actual changes appear to be for Enchanting. There are some new recipes available from the trainer which I haven't seen yet because I didn't copy Kayree to the PTR (will do that later today). And it looks like Blizzard finally figured out that no one wants to raid old dungeons anymore, so they are opening access to the AQ recipes. Presumably this is to get those recipes into the hands of more crafters without requiring AQ runs. The bummer of the deal is, they've chosen to do it in the same style as the Alchemy flasks. So far every one I've found has required Exalted reputation to purchase. Not exactly casual-friendly, but I guess they don't consider Enchanting a casual-friendly profession??
Blizzard has also decided to modify the components required for some of these enchantments to bring them more in line with the expansion materials. I guess they also recognize that we don't have old ingredients anymore and it's annoying to have to farm old zones to get them. I don't even use my Enchanter except to enchant BoE items for my other toons and she is already out of several key ingredients for older end-game chants. I'm sure we've all noticed that the AH prices for these things are sky-high as a result.
We're also getting some new recipes from the Violet Eye faction, thank goodness for that because those folks were being rather stingy. There's a new Alchemy flask, a weapon enchantment and a new cloak pattern for Leatherworkers (neat!). Here I thought they'd totally forgotten that Leatherworkers could make cloaks, silly me! I don't yet have the stats on these new items, but I'll post them when I find the item info.
There are also a handful of tooltip modifications on various crafted items, and that about sums it up for the 2.2 crafting changes.
