The TBC era mega-patch, which appears to be the model for the Wrath era, really shifts the focus towards major, headline grabbing packages that just so happen to contain something for everyone. My wife's druid is still level 50, so she doesn't care about new raid content and may not have access to dual specs (Blizzard may be considering backtracking on their plan to limit them to the level cap), but she admits that being dismounted by riding through some shallow water and having to stop to remount was irritating. It's a pretty sensible guess at a business model when you consider that there are probably more former WoW players than total players of most other games out there at the moment.
Still, this is the first time I can remember a blue poster saying anything like this from Ghostcrawler, the face behind most of Wrath's class balance (emphasis mine):
Although WoW is a gigantic game, some players are just going to voraciously devour whatever content we can throw at them. There are certainly a lot of different ways to play the game that you can experiment with if you do get bored. I would suggest things like trade skills, achievements or completing all of the quests you might have skipped. Collect some offspec gear and try a different role (in PvP or PvE). Rerolling can also be a lot of fun. If you're just burned out, it's also not the worst thing in the world to try out some other games -- the past couple of years has been great for them. Just check back in with WoW every now and then. :)
It makes sense, as Blizzard is still going to make money off of players who are subscribed for a few months at a time after major patches. I'm just surprised to see that we're actually at the point where even Blizzard employees are actually suggesting that their own customers might want to leave WoW in between patches.
