As I mentioned, I'm re-leveling jewelcrafting on my live server (Llane) and I took notes on a few of the changes I noticed.
1) Prospecting no longer gives skill ups at any level :( This means for the folks using the guide you need the rough stones (150-200), the option to use prospecting for points is gone. If you don't want to use stones, you can move on to the first jewelry recipes sooner and adjust your materials to compensate. Luckily I had the rough stone and was able to get all 10 points with my stash.
2) I miscalculated the number of required Shadowgems on my shopping list. The second section requires 20, not 10 as listed. If you opted to make the Heavy Jade ring then this error wouldn't apply to you. For those who were planning to make both shadowgem recipes you'll need 40 total, not 30.
I also noted the gem drop rate on Iron ore was much skimpier than other ore types. So if you're counting on prospecting iron ore for missing gems, bear in mind that it could take more than the 10x per missing gem I previously suggested.
The same applies to Thorium, but not for the same reason. I prospected over 200 thorium last night. The drop rate was very good, but I still had trouble collecting the opal/sapphire/diamond/emeralds I needed. For some reason I got way more rubies than anything else, which should be a mithril gem. I also got about 10 Outland gems, so I guess that was a nice bonus. But it was still annoying to prospect so much thorium and end up with more lower tier rubies than any of the equal tier gems I actually needed.
On a positive note, I prospected a bunch of mithril ore and made a chart. I'll post that up later as well.
Hope everyone is having a blast in Outland!!
