I've had Auditor disabled since the patch, so I'm not sure exactly how I'm doing on gold, but I can tell you:

1. I am selling tank gems like crazy. Largely Solid Ocean Sapphire (+60 Stamina) and Puissant Dream Emerald (+20 Mastery, +30 Stamina). Although I've also sold a couple Fractured Amberjewel (+40 Mastery). Still selling Demonseye and Ember Topaz uncut. Red gem prices are up, but I admit I'm a bit stingy with my rare red gems now that they're not free anymore.

1a. In all the to-do over cut uncommon gem vendor prices falling, nobody mentioned that rare uncut vendor prices rose. Uncut rare quality gems now vendor for 5g each, same as their uncommon-quality counterparts.

2. All my alts that can cook are doing the cooking daily, and spending their Chef's Award on Cocoa Beans. All beans are sent to my only 525 cook, who makes some Chocolate Cookies, and throws them on the AH. Not tons of gold, but it's gold.

2a. I need to make a reference of all the new cooking dailies and their rewards. Since you can only do one of fishing/cooking from the SW/Darn/IF set, it would be in your best interest to maximize rewards by choosing the right city each day.

3. With everyone rushing back to their 85s to try out the new dungeons, low-level mats aren't selling quite as well. (People aren't playing their lowbie alts right now; they're too excited about the new stuff!)

4. Portals to SW and Org have been put back in Shattrath (near the portal trainer) and Dalaran (in their old locations). Adjust hearthstones accordingly.
