Not to be a Debbie Downer, but the reality of a class action suit is unrealistic.
And if you think NCSoft would "settle" and give up an IP worth millions you are sadly mistaken. The most an individual could sue for is the amount they are out; with an upwards limit of $100 (Read the User Agreement people). While many want to argue that the User Agreement is not valid etc etc - it is a legal contract that can/will be upheld in court. Getting past the User agreement will require some pretty darn good legal strategist.
If there was a class action lawsuit you can only claim for unused sub fees (not paragon points fyi...since the market was left open for you to be able to spend thos epoints....). And my total amount of unused sub fees: $0....which is one reason they gave a 3 month grace period instead of shutting the game down on 8/31/2012...to use up some sub fees of those who subbed for 3/6/12 months.
Realistically let's look at this:
The absolute MOST a person could claim would be 9 months IF they completed a 12 month sub on 8/30/2012 since the game is open until 11/30/2012 (3 months). 9 months @ $15 = $135. How many people did that... a handful maybe. Most people will have 2-6 months left if they bought in bulk once 11/30/2012.
I'm sorry but I do not think any lawsuit in the end will bring anything close to what people think it will...except a long drawn out "battle" with verrry little "reward."
Unfortunately, I agree with Burnt Toasts.
However, if it means that I would get MONEY back instead of game credits, then I'm in.
Because, I do think it is a case of bait and switch if I signed up for CITY OF HEROES credit specifically and then am told, "You can use it for Guild Wars 2".
I liken it to going into a McDonald's:
"I'd like a Big Mac meal, please."
Cashier: "Okay, your total is $4.82 and your order # is 17."
A bit later...
Cashier: "Order 17, your order is ready!"
I approach the counter.
Cashier: "Oh... we were out of the sesame seed buns, so we're giving you a fish sandwich meal instead."
At that point, I'd ask for my money back.
I do realize there is no EULA at McDonald's, but I can't help believe that there MUST be something to protect the consumers.
Or... I would contact NCSoft and say, "Trust me...you don't WANT me going to one of your games. Your broadcast channels wouldn't hear the end of me."
