If SE wants to get more subscribers perhaps it would be better to not discourage them from signing up during the free trial. I was running around with a friend who was trying the game out and he kept rattling off the RMT tells he was getting. Someone who despises RMT isn't likely to stick around when the advertising is so blatant.

People stick around in a game for various reasons. Some care about cosmetics, some don't. Some care about raids, some don't. Some enjoy leveling slowly, some don't. I don't think anyone loves RMT ads.
