This DLC feels kind of like a rip-off. While it is nice to have more things, like currency or gems in your game by paying money instead of grinding the game into oblivion, what is not cool in this DLC is that it gives you gems randomly. It is equivalent of the slot machine - you might end up with exactly what you want or tell your money goodbye and throw it down the drain, since you didn't get the gems you wanted. It is really hard to rate this DLC, since it's rating depends on what you will get. If you will end up with bad gems, there is nothing that will help you other than trying again. If you will get what you want it is great. If you're feeling lucky, it is recommended, if not, try your luck grinding.
