Back in the day before WotLK came out, we (the handful of us hunter posters over at EJs) laid everything out to Ghostcrawler about how BM base was too high and scaling was too low. How we'd win the patchwerk fight in Naxx so badly that BM would be overnerfed and bad for the rest of the expansion.
We got forum banned from the Blizzard forums and told we didn't know what we were talking about.
And then everything happened exactly as we predicted. I think our theorycrafting back then was even accurate to within a few percentage points of the logs.

Even if they had gone troll for DPS, you can't just switch to MM without the gear and you can't just switch to an alt that isn't properly geared up and funneled to.
I am surprised top guilds haven't banned hunters and shamans outright though, just because of mail gear and ease of sharing.
