Of course, something that shiny is going to attract admirers and tons of people who want one for themselves. The issue crops up every few weeks on the general forums or the suggestion boards: Someone wants a crafted flying mount of their own without switching professions. If they got themselves up to 375 in their chosen skill and want to spend another thousand gold or so on expensive trade skill items for a flying mount, why shouldn't they? It'd be a great way to show pride in your trade skilling prowess and give one more way to shed that plain old Wyvern or Gryphon and set yourself apart from the crowd. You could go with, say a nice flying carpet for the tailors, maybe a flying mortar and pestle for the alchemists. Now, I tend to agree that it's probably good enough that Engineers are unique in getting a flying mount in the same way that, for example, Leatherworkers get drums or Blacksmiths get weapons and armor. But then again, I also have to say that Engineers already get some pretty awesome goggles for a unique reward anyway, and a flying carpet would be pretty sweet.
So what do you think? How about a leather-winged glider for Leatherworkers? Or do you think that it's enough that the Engineers have a mount that's taken from previous lore and people should stop asking for silly stuff that's never appeared in Warcraft before?
