I see cash shops in an P2P MMO only an issue if A)it effects game balance by what is sold there such as buy to win or B) the company is producing product for its cash shop while their paid game is failing to provide its money's worth for the subscription. I find neither of these an issue with SE. SE provides very good value for money for its sub fee, probably being one of the most prolific content providers in the industry and nothing on the cash shop is more than vanity or convenience.

Do people genuinely feel they aren't getting their value for money for their sub? Cause it that's the case its not the cash shop's fault. And if you are getting value for your sub then why are you complaining that your not getting even more?
