In this case, the title says it all. I don't think I know a single player who doesn't at least occasionally think themselves smarter than the game's development team, so I ask you this: if you could change one aspect of World of Warcraft, what would it be? Does the PvP system frustrate you? Is the endless reputation grind no fun? Is large-scale raiding not your thing? Is the game just right as it is?
If you were on Blizzard's development staff for a day, what would you change?
