WoW's retail expansions have served one major purpose thus far: to reboot the game, usually to make it more accessible as a whole. The Burning Crusade did it by chopping the upper raid limit, shaking up a lot of players in the process, and Lich King follows in similar footsteps. Certainly, WoW is going to keep changing in the months to follow, and hopefully, what comes down the line will build on the remarkable world that Blizzard has put out with Lich King. But at least until the next expansion rolls around, these environments have enough life in them to keep gamers all busy for a long time.
