It's extremely sad what has happened to Blizzard. I still play the game and hope for a change, but don't think it's ever gonna happen... The game has really gone to shit. Just read a blue post on the shop mount earlier today aswell:
Production takes a long time, and we have them on a regular release cadence. You can be certain than every few months there will be a new store mount.
If someone buys a mount off the Shop we don't want there to then be confusion as to whether it's the Shop version, or a recolor obtained through in-game means. We essentially purposely ensure shop mounts stand out as shop mounts.
Just throw everything to the shop and collect $$. And it doesn't even matter if 99% of the players don't buy them, they still make shitloads of money from them and will keep doing it. Just gonna have to suck this shit up or stop playing pretty much
