Why is the Cruise Chaser mount from the Mogstation?

They didn’t make it though. It’s already in the game with the animations and everything that’s why this is such a big deal to people. If they made it sure. But it’s an in game entity.

Sure but it still takes time and resources to do, something they most likely aren't going to spend on making a mount especially during crunch time before an expansion is due out. Its not like they take the assets and slap a line of code to it and be like okay people can use it as a mount now.
