I know it's your opinion, and I respect that, but this "type of behavior" has been going on for years now. Blizzard isn't paving any new paths with this. Frivolous DLC has existed for a while, dating all the way back to the infamous horse armor.
I guess I just don't feel that affected by it, nor do I envision it being the downfall of games. It's merely another revenue path in a business model where it has been shown that people are willing to spend money. It's a smart business move.
You are right, but the difference is this: Blizzard is a giant when it comes to market penetration and sales. So if Blizzard simply kept its mouth shut, didn't give people the ability to deduce how much in sales it has generated from this little paid DLC, then other companies would not know just how successfull this was. This money, is as close to pure profit as you can get. There is no 'box set', there is no distribution system other than bandwidth.
But, I also agree with many of you when you say a hobby is a hobby. I enjoy playing an MMO, but paying for my service (I look at it as paying for bandwidth, honestly) is all I will do. I won't be spending money on their little gadgets ever. In fact, once an MMO starts doing that, I typically exit.
I also feel that going to a movie is a waste of money, especially in the evening. You can blow $20 bucks for 90 minutes (oh wait, 120, I forgot about the 30 minutes of previews) of viewing.
But these are just 'my opinions' and 'my hobbies'. Others are different and I respect that. but I don't respect Blizzard charging $25 bucks inside a normal MMO billing model. Again, I understand no one is forcing people to buy the horse, but they prey on people's "I gotta have it!" addictions. :-(
