If enchanting sucks in PVP then might I suggest going engineering?
Seriously though, enhance is best in turbo cleave to spam purges. Elemental is garbage (what's new). Resto is the only way to go... So if ur not having fun now, you're probably not gonna have fun later. I suggest shelving the shaman and pulling out...any other melee pretty much. Sorry man but its the life of a shaman and you gotta get used to it.
