While I think that MB'ers are a niche group in the WoW population as a whole, I do feel that as Blizzard has "dumbed down" WoW it has really lowered the bar for players and at the same time elevated expectations on what the "average player" could accomplish.

If the frustration of the average player is even remotely similar to what we are experiencing, I expect that Blizzard will not go another 6 weeks without nerfing the hell out of heroics, increasing the rewards of heroics, or (more likely) both. No matter what Ghostcrawler thinks, enough account cancellations will speak more loudly than anything else.
