I am really sad with this decision. The skins are looking awesome and I was about to buy some of the pet skins. Now I am hearing that the rarity affects the stats, I am not going to buy a premium egg until they changed the system. I understand you don't want have pay2win but now they let us gamble ( with real money) to get a descent pet with the rarity we want. This just looks like money grabbing and I think and hope it is unintentional. The few solutions I can come up with are: When you transform a egg in a premium egg it will be the highest rarity. The downside is that it is a little bit pay2win but you still can get legendary eggs the normal way. Besides the premium eggs are not stronger then the regular eggs. at least we are not wasting real money on crappy pets. let us apply the skin to our pets just the way we can apply customs to our characters. I don't know if it is possible and if it would make sense.On the other hand some of the costumes also doesn't make sense :P Let us transform the pet instead of the egg. So we know what the pet is we are transforming then it is our own choice if we choose to transform a crappy pet.
