It's funny, people complained because hunters were overpowered at 60 when they got all their new goodies from the 41 point talents.  Well that's a different discussion but the thing is with so many hps, hunters dps isn't scaling the same as the hps people are adding to their characters with the expansion.  So now, my 1200 arcane shot crit doesn't put quite a dent in someone with 7000 hp and then add in people with resiliance on their gear so I don't crit as much...

Ah well, what can ya do?  The nerf pendulum swings both ways eventually.
