I was pretty fortunate. Got it on the first run. It totally blew me away because I had heard it's a relatively low drop chance, so I went in there planning on having to run it a lot. I had completely put the pet out of my mind to the point of forgetting it dropped, when... HOLY CRAP! I'll run it some more to try to get one for sale or trade.
Yea, I got a feeling I'll get sick of running it. But I need to get the pet from a drop. These damn Garrisons have bled all my gold dry. I seriously got nothing left.
Don't worry, you'll make it back pretty quick. Gold just seems to pour in in this expansion - especially if you have the right buildings. The Salvage Yard and Gladiator's sanctum are pulling in a lot of junk items, and the Salvage occasionally turns up some very rare AH worthy items. You can easily make 10k a week, or at least in a couple weeks, without even touching the AH. Now that I have all the buildings I need to lvl 3, my goal is to save 300,000g for a mount. The sad thing is that there are people who could easily make that much off what I have rotting away in my guild bank, lol.
