So our question today is: what's your favorite or most important crafting item? I'm in the middle of leveling my paladin, and he's just now reaching the highest reaches of Engineering, which is a skill I've never leveled up before, but have always wanted to. I haven't gotten together the gold for epic flying yet (well on my way at level 73), but I did make normal flying machine as soon as I could. And my big goal with this character, other than getting him raiding ASAP, is to make the Mekgineer's Chopper -- ever since we first saw it in the early days of Wrath, I've planned to get a character up high enough to make it. I know, I know, I can buy it, but for me it's a crafting thing -- I want to go out, find what I need to find, and craft it with my own virtual hands.
Any other crafted items that have you wanting to make something for yourself?
