When I read on Warcraftrealms that players have been steadily leaving WoW since the release of the expansion, I admit surprise. There is so much content in TBC I can't imagine anyone getting bored.
I can already hear the heckling from the back of the room as I say this, but think: the top raiding guild just downed Illidan. Exactly how long will it be until an average raiding guild, let alone a casual one, will be able to accomplish the same feat? Love it or hate it, the expansion increased not only the lands we were able to visit, but the quest lines we could follow, the races we could play, the factions we could prove ourselves to. I am overwhelmed by the amount of things I have the opportunity to do in the game now, to the point where I have trouble picking most times and end up bouncing between doing my daily quests on my mage and leveling my Draenei priest.
Why then are people leaving the game? Is it that they see it as something conquered once you reach 70? Is it that despite how much content Blizzard puts out it just never is enough? What do you think Blizzard can do to stem this downward spiral?
