It's not a nerd rage to be disappointed and upset that we paid for a product and service that is now not being delivered. It's like me ordering a pizza, paying for it by credit card in advance and the pizza never shows up.. Lots of calls to the restaurant assure me it's on its way, but the fact is, they are failing to deliver the product they advertised that I have paid for.
And while I know in 2005 WoW had technical difficulties and other games following, this is not a valid excuse in 2013. MMO's are nearly 20 years old if you count the old MUD's. Saying "everyone has a bad release" is like expecting there will be a few fatalities every time a new model of car is released as if no one understands the basics of how frames or brakes are manufactured. New games should be based on years of experience established by previous titles. Server loads and architechture are tested in beta. catastrophes are expected in beta.. That's what beta is for. This is no longer beta.
What's even worse is that this the second release of this game. They already had a trainwreck in 1.0, we gave them a chance to fix it, and we got this instead.
I'm not saying people should be rage quitting and destroying things IRL, but I think people grieving their anger in these forums (run by SE) is completely justified.
