The only thing I ever sell is the Legion Medallion rep item from WoD Garrison missions (5-8K, depends on the day). I have 12 Class Halls which I maintain 2x a day from my phone.
I've got nearly 9M Gold, nothing to spend it on, so yay this. I think I will actually buy it. Never bought the damn spider, because i despise them. It's still very odd to me that they made the Legion goldsink mount something many people have a visceral reaction to.
Basically everyone loves Dinosaurs. Smart.
