What if instead of a normal cash-shop, you have to "unlock" certain options?

Just a thought. As a HUGE fan of Odin, even though I bought Sleipnir, there's still a part of me that hates using it, because I know it's "just a cash-shop mount". But if it was, say, tied behind an "Unreal" version of Odin? Then I'd be pretty stoked about it!

And would you be more "stoked" about paying $30 for your mount unlocked by defeating Odin than to simply receive it as a reward for defeating Odin?

Achievement awards should come from achievements. The cash shop is for cute fluff that doesn't prove anything except your ability to spend money on it.
