EDIT: Apparently this transmute *does* share a cooldown with other transmutes outside of the TBC transmutes. So again I would check prices on your server and make sure it's worthwhile to have and use this transmute instead of certain other ones. I believe it shares a cooldown with all other daily transmutes, even those that aren't listed in the profession text as a daily cooldown in game. Kinda unfortunate, but again I'd say compare prices and check the stock of Primal Air on your server because it could still be a great transmute to have if the stock is low on your server.
Hey Bunnycuddle, big fan of your approach to gold making. Due to recent drop in obliterum market prices i have started exploring the best flipping possibilities out there. I found one very interesting phenomena that proved to be very profitable on my server. Basically due to it being least desirable gem Versatile maelstrom sapphire tends to drop in price on AH well under 160g per piece, and while oblierated it gives 16 ash in return. I think this is something you could possibly research in your future post and give a little bit more in depth analysis.
If i start on a new realms, I am farming a lot of transmog from classic and Burning Crusade Dungeons and Raids. In the beginning, i start to post them if they have at least a DBRegionMarketAvg (Average value of an item on all EU realms of the last 14 days) of 500 Gold. All the other items get vendored. The time you hit a stock of 1000 Items, my value treshold raises to around 2.500 Gold. All the items below that value get vendored aswell. Newly farmed items that are above these treshold will be listed. Why? If I start over somewhere, I want to get a certain amount of gold quickly. Cheap items are great for that. Later on, to save time, Quality is better than quantity. As mentioned above, re-posting the items on the auction house takes quite a bit of time. At this point, I can recommend you the TradeSkillMaster AddOn, it makes your auction house work really a hell of a lot easier.
