Weapons are the most defining characteristic of an enhancement shaman. If you're in Orgrimmar and you see two friendly Tauren decked out in Erupting Volcanic gear, you look to the weapons to tell them apart. If they've got one weapon and a shield, they're a caster and probably not worth inspecting (especially true in the case of that Lodur fellow). If they're dual wielding awesome axes, fearsome fist weapons, or magnificent maces, they're a true shaman.*
When transmogrification was first released, tier gear was the talk of the town. Black Temple groups were organized, classic raids were soloed, honor was hoarded for Burning Crusade PVP sets. To me, though, armor is just a backdrop. It's the scenery behind the Mona Lisa. The picture wouldn't be complete without it, but it isn't the focus. While the rest of my friends were obsessing over tier gear (except Tyler Caraway, who will still just look like a boomkin 24/7), I found myself agonizing over one simple question: Which weapons would I wear?
