I missed a couple weekends of cooldowns due to a good amount of travelling, so I was behind on my Sky Golem, finally got it finished last week. While I hate the fact that everyone and their mother has one now, and uses it.. I still think its awesome due to its Engineering subtleties: the metal, sounds, effects, moving parts.. its the reason I still use my flying machine on my Engineer. So.. obviously I learned it for myself.. by the time I had it complete, the market for them was basically dead and not even close to worth selling off.
One side note: I sorta wish it was Engineering only to use, I like unique mounts that are difficult or impossible for others to obtain.. again another reason why I still use my flying machine on my Engineer.
