I dont think there's anyone on this forum that doesnt know that WoW is focused heavily on end game. What make me wonder though is why blizzard bothers to keep adding levels and quests every expansion if the game is about max level raiding anyway.
Just think about it. less quests and levels = more relevant end-game content. Why bother making a quest line in Shadowmoon Valley if they could instead make an extra raid encounter or two. Right guys?!
