This is the official response regarding the mount. Given their reasoning, I doubt they will change their minds. Of course, nothing is certain in this game but I can sort of understand what they are saying. Its a big thing, the biggest mount in pure height of any in the game, and if they were permanently put back in, and considering how much gold people can raise, the game could become incredibly littered with them. Imagine a hundred of them sitting next to a mail box or some other popular location…
I think a better idea would be to create some form of toy that provided access to an auction Blingtron for a limited amount of time. If you could call it up and have it stick around for say, 10 minutes every hour, that would provide auction assessibility to everyone and not create a visual issue.
