This is the complains with MMO's for so long. Stat-based cash shop is straight up bs, indeed. At least they are learning lately. They are either going freemium or going with a model like League of Legends, where you can only buy boosts and skins. Boosts aren't that gamebreaking, though. Most are even fixing their cash shop after numerous complains, for instance Allods. The western free to play market is really picking up to this lately.
