That's a real tough question... Hmm... Ideally, being a mage was always my first pick, I mean, it's freaking magic! What race is a tough one though... Nothing wrong being human. They look the best in robes imo, together with elves, their bodies scream cover me in a robe. And muscular bodies in a robe isn't really that good looking imo
(pony tail whirling around apple crumble) On the other hand... Bein a freaking rogue rocks, plus being orc is a natural good looking quality...
But if I my personality, skills, talents and body would be the same in warcraft as irl... I would go for either human mage or blood elf. (looking like link from legend of zelda banana split) Although a rogue is sneaky, patient and relatively safe... Which also suits me... Plus I tend to scare people with irl sneaking abilities. Orc's culture would be too agressive and intimidating for me. I'm too much of a softy ;_;(plus i wouldn't last for a day in a real orc culture)
