Pretty much. I personally play a little different, but those two builds are the most widely effective for most play styles.

Back when I played hardcore, I had a Marksman specced Hunter. If you can get some decent gear with +AGL, +AP, and +Crit, you can do some insane burst damage for PvP. Aimed shot, Improved Concussion Shot, then kite. They're dead. Course, that was before Death Knights and their Grip spell
