But when is the line crossed? When you can be filthy rich , buy a crap ton of EP turn that into gold and when the auction house comes out , you will buy a ton of mats getting to level 45 in many stats in a single day. Basically meaning that you are buying stats with real money, which would take others a weeks or months to do the same legitly.
That sounds like a Pay for Convenience not Pay to win all the current cash shop features just speed up your leveling and progress there is nothing a none paying member cannot do the same as EP buyer its just they get it faster.
