The animation is great.
I'm not opposed to the Cash Shop by any means, but why must you put these in the cash shop?
zOMG! is probably the only thing on Gaia that you don't need to buy things for. I especially liked that you didn't need to buy rings from the Cash Shop. It figures that the best rings would be put in the Cash Shop, but wouldn't you appeal to newer users if these great rings were dropped or achieved throughout the game?
Again, I'm not opposed to the Cash Shop, but zOMG! is a lot better when you win the item in the game, not bought with my hard earned money. I could buy dinner with that five dollars.
Edit: I hadn't realized they would be unsoulbound. I, personally, wouldn't buy it for five dollars, but seeing as it's unsoulbound, than yes, I think you should sell it.
