Blizzard lost all credibility when they sold the guardian cub, allowing rich people to buy gold from other players for real money.
But even as far back as when they sold the celestial steed, people were saying it's all cosmetic so it doesn't matter. Nonsense. Even back then I had argued that cosmetic microtransactions could get out of hand, and now they have. With this change, why not add the following:
1. $15 for improve spell graphics and animations.
2. $15 for armor dyes.
3. $25 for updated character models.
4. $30 for adding glows and sparkles to weapons and armors.
5. $40 for dance studio.
6. $60 for player housing.
7. A real-money-to-gold player-driven AH to provide the same functionality as the guardian cub.
This is completely outrageous. They are using subscriptions to fund the development of content to sell it again. They're selling what's already bought.
