Low percentage!!!!! I am more likely to be hit by lighting. But really in other MMOGs there are tons of appearance items to buy, potions, mounts, and etc and you can buy them and know exactly what you are buying. Spending a real 15 dollars for pet food is not my idea of a good deal, it is a rip off. Trying 6 times times 270 AP per try. AP equals about 110 - 140 points per dollar. 2 x 130=260. In the end that equals around 12 dollars for nothing. In most MMOGs that would pay for almost a month of pay for playing. I would buy more but not when I do not know what I am going to get.
