Seems like a lot of angry people in that thread, but I'm not sure what they expected?
Combine the surprise of transience with the use of real money to buy fake goods and it can be a true shock. This is especially true for casual gamers who have yet to experience their first game shutdown.
I was realistic and didn't spend that much, but I can't imagine I'm the only one to feel that way. I've now got an even stronger stance against online only games/communities.
It makes me really sad to think about; WoW (and video gaming in general) has been a huge part of my life and tinkering with video games under the hood was the kickstarter for my career. I don't know if I will ever find a replacement for it when it's gone.
