In WoW, if you played correctly, Hunters can be real monsters in PVP. So to succeed though, you must follow three rules.

 
1) Keeping out of range of your opponent is the key to your survival and success. Even though it is small, a hunters deadzone will quickly live up to its name, if you don't move enough.
2) A hunter must choose their targets carefully. When fighting in group PVP you are better off going after targets that you will have the easiest time killing. This is mostly casters and classes with low armor.
3) Remember your role. A hunter can play offensively or defensively. When fighting offensively your primary concern is working with your group do deal as much damage as possible.

While, when fighting defensively your primary concern is survival and hindering the enemy. Fighting in PVP is similar to fighting in PVE except that the enemy has no concept of aggro and will act more independently. Since you have no real way of healing yourself and your defensive options are somewhat limited your best bet is to damage your enemy down as quickly as possible with high burst damage.
