Gear gives you a lot more power over the rest of the population than leveling does. This isn't EQ or FFXI where leveling can be the majority of the game. Leveling is a stepping stone. It doesn't matter. Also, the only difference between the boosted character and a character boosted through RAF is that the RAF method is more convoluted. And I don't remember this many people having a problem with RAF.
Since 99% of this game is spent at max level, selling levels isn't selling power. But selling gear is.
