EQ2 and WoW have been out just about the same length of time. Which team has put out more patches? EQ2 by a long shot. 28 to 9 is the score I could find.
Blizzard needs to change their frame of mind regarding content updates. They are moving too slow.
This is part of my fear, that the overwhelming popularity of WoW is very very bad for the game and possibly the genre. Everyone used to copy EQ, now they will start copying WoW. Granted, WoW is fun, but for how long?
Blizzard is sitting on a cash cow, what is left to motivate them?
