The answer is simple it's a business move. We have people who are dedicated to this game because they have more free time and they can achieve coil gear. Now in order to keep casual players feeling like they are not far behind the hard core players they give them gear as well. Other wise a casual won't feel like he can ever catch up because he doesn't have 12 hours a day to play. And if he feels like he can't catch up he will quit. And quiting means no sub's and no sub's means no money for square.
