The Perils of "WoW-nnui"

Terra Nova has an interesting piece

up about what they call "WoW-nnui": After stepping away from WoW for a while, Mike came back to the game experiencing ennui. Don't worry, I had to look it up too-- ennui is "a feeling of utter weariness and discontent resulting from satiety or lack of interest." Coming back to WoW after a long break can give you exactly that feeling-- the thought that you've seen everything there is to see and do in this game and you're just plain done with it.

Is that possible? Of course it is. If Blizzard has failed to hold your attention (even after an extended break), then they don't deserve your fifteen bucks anymore, and it's time to quit. But ennui isn't always the end, as TN suggests-- lots of players have gone through it, even after a respec, or (to a lesser extent) after a particularly comprehensive revamp. And for me personally, even if I'm faced with a little boredom after a long break, even a short bit of grinding usually gets me right back in the thick of things, looking for loot and XP.

Now, as TN notes, anybody experiencing "WoW-nnui" at this point will probably be back for the expansion anyway, and there's a whole slew of games waiting in the wings to grab anybody walking away from WoW. Obviously, Blizzard has an impetus (see? I can do it too, Terra Nova) to keep ennui out of the game, or at least in control. Is it out of control? When you come back after a long break, are you back in the game, or thinking about getting out of it?
