The prices for items on the cartel market is just way too high. Do you really expect people to pay ten to fifteen dollars for an armor set or color crystals? These prices need to be somewhat reduced. The cartel conversion from cash to cc is fine, but lower the price of actual armor sets and crystals a bit.
Who gives a damn if freemium players have to pay $10-$15 bucks for armor sets and color crystals. Serves them right for not subbing.
Subscribers won't have to pay anything to get those items. They can easily save up their monthly stipends and get anything they want for free.
