I do see that side of the argument, and I agree to some extent (I wouldn't want armor sets being sold), but you can do both without compromising the game's integrity. Guild Wars 2 does this with transmutation stones (keeping one item's stats, while using the looks of another), town clothes, minipets, and accessory items. As seen in games like GW2, LoL, TF2, etc, some players will spend thousands of dollars on frivolous cosmetic items. It's also part of the reason that games like League of Legends, DotA2, and SMITE are so successful. If people are willing to spend that much on items like that, let them! Carbine Studios is a business afterall. I have to disagree with you here. GW1 was an early pioneer of the buy-to-play/free-to-play model. A much better example is GW2 - it's buy-to-play, but the developers have already released a large number of free, high-quality updates (for example: the halloween event, the Wintersday event, and the retro N64 game inside of GW2), and full expansions are coming soon. All this while still being extremely profitable. I don't think even WoW has had such awesome content updates/events for free.
