Here are two pretty sick Hunter Specs for the WOTLK.
PVE(Bm): WorldofWarcraft.com -> Info -> Classes -> Hunter -> Talent Calculator
PVP(MM): WorldofWarcraft.com -> Info -> Classes -> Hunter -> Talent Calculator
The PVE spec is your Basic BM spec, however it includes the new tame ablility in which will come in handy and be fun to use
The PVP spec is a new type of Hunter spec. Usually hunters are Brust/Overtime killers. With this spec your hunter turned into a DOTTER! Thats right, with the new MM ablilty your hunters stings not only do damage over time, it brust dps's like crazy!
(Q) What is with this PVP spec, it looks noob!
(A) This pvp spec turn the hunter 180°. Instead of a hunter being BRUST/DOT the hunter becomes a DOT/BRUST class. Increasing damage done to the target. Seems like a PVE spec, but it truly is pure PVP.
