Gated progression is bringing WoW back to an epic raiding experience. It was a smart move by blizzard because it gives all players not in the top .05% something to believe in as a worthy accomplishment and serious appreciation for these elite achievements. If the game gets too easy then there isn't any reason to push yourself, as a good player, to new levels of expertise and skill. Wotlk is a work in progress and a worthy usher for what many of us will consider to be the "Golden Age" of MMORPG raiding.
