Why bother killing someone if you can't look good doing it? We all know that's our real job as Shaman. Not buffing, not DPS'ing, not healing. It sure as hell isn't PvP'ing.
Me, personally, I saw my reflection in the fountain in Iron Forge and I thought, "Wow. I am really, really, ridiculously good-looking. Maybe I can do that for a living: be professionally good-looking."
