I'm looking for a class/spec that's good in pvp but also high demand in pve

Basically, the title.

Also, that means not warriors/paladins.


EDIT: Pertaining to wotlk

i guess warlock? maybe

Hunters, Warlock, Priest, Shaman.

Hunters? That's all I ever see though, and I often see raid advertisements saying "Full on hunters"

Thats a bit tough dps wise considering all the good dps is usually good at pvp and is thus not in high demand for pve. Warlock or healer would be best choices
