Didn't start off the xpac with much, maybe 5-10k spread across all my chars. Over the last six months though, I got pretty lucky with TCG mounts and have made a total of around 500k. Down to about 150k across all my chars now. Spent most of it on other mounts(Jeweled Onyx Panther, Mechano-hog, Traveller's Tundra Mammoth, etc.) and leveling profs.
