A lot of people don't understand the concept of 'overpowered', yet everyone loves to say it. They're not overpowered simply because they're priced so high. If, let's say the PBP, were priced at 30k and not 125k then fine - it's overpowered. But because it's priced at 125k, it deserves all the power it has. You get what you pay for.

And like Snake said, that doesn't make this game pay to win since it's not impossible to earn the Gralats yourself with a little work.
