Pros and Cons of Making the game Pay-to-Play

There is no way of turning GMS or any other current MS server into Pay 2 play, because they couldn't take out of the game all the advantages given to people that pays without affecting those that have already paid to them. However, in the scenario another version is created, I believe it would be the best idea in a way to eliminate all the advantages given through money as the way to fund the game, as long as the company running it can guarantee or at least can be considered capable of handling the list of issues that plague all other MS servers, specially refering to exploits that allow to generate mesos and items. Because now every character would be a customer instead of a guest to them with capability of becoming customer, they need to convince the,m that the money they are investing is worth it (although I must admit thats not mch different from how things should alreadybe).

That would come to solve one of the big issues of the game, there would still be left the issue of KMS focusing only on developing new classes and upgrading old systems, instead of adding new content or this one being lackluster when they do.
