There are groups now for reformed players to get therepy, I find it weird.
Personally i've tried the 30 day trial of it and I wasn't that impressed. I'd rather stick to playing warcraft 3 online than have to pay every month to play WOW...
I know a few people who are really addicted to it, and a few who used to be but stopped due to problems (mainly money...).
Blizzard must be making loads from it though. They seem just to be milking it now for all it's worth.
After playing it I really can't understand why people would want to pay quite a fair bit of cash to keep playing it.
Guess it's a love/hate type thing.
