I used to remember the days when Blizzard would swear up and down they would never offer ingame items for real life money. Eventually they did, offering better mounts and pets that are obtainable in game, but it's all good because they're non-combat items right? They swore they would never offer ingame equipment for sale with real life money because it ruins the spirit of the game. Now they've done so with D3.
There are so many other things they said they would never do, like PVE->PVP transfers, both factions on the same server, etc., what reason is there to trust them on anything they say? This is especially true considering everything they've ever changed their mind on directly concerned things that would make them more money.
