Well, you'd think that, anyway. Word on the street is that there are already Death Knights at level 80, and all the raid content in Wrath has been completed. One player reached level 80 in only 27 hours. Over a year of development for one week of content? Are MMO players just too damned hardcore, or did Blizzard aim too low? How much content should you be getting for $30 or $40 and your continued subscription, anyway?
There are some folks out there who (to continue using WoW as an example) are still hacking through The Burning Crusade's content, or even the classic stuff. How do you think a balance can be struck between those folks, and the crews who have already bested all the Wrath content?
