WHU: Beta Hunter Nerfs  Frostheim at Warcraft Hunters Union:
After the last beta patch with a bunch of hunter buffs, it was
quickly apparent that hunter dps was too good. So much so that
hunters themselves started pointing it out on the forums.
Blizzard responded that they were aware of it,  You are soon
going to see damage go down for several classes and specs in
cases where we overshot our targets or fixed bugs that required
adjustments. Hunters are likely among these. I am mentioning
this because what inevitably happens is a host of posts across
the Internet saying that x is now gutted, won’t get a raid slot,
needs to reroof, was middle of the pack at best, and so on. It
is most helpful to us if you want to argue that your DPS is too
low (or high if you are being unusually honest) that you are
specific about what situations you are talking about, against
who you are comparing numbers and what those numbers are. 
Shortly thereafter we got another patch that did indeed include
a nerf — dropping Arcane Shot
