My enhancement shaman hit 28 today. I'm considering doing some pvp with him, but he's not twinked or anything like that. I have some general questions about PvP at this level.
1) Should I even try, or will I get steamrolled by twinks at this level?
2) Is enhancement viable pvp at this level?
3) Is there any gear that is purchasable that is particularly useful for an enhancement shaman at this level?
4) Is there any low level pvp gear that is worth saving the marks for?
