Humans tend to be the ones in the middle. Not as sexy as the Night Elves; not as stumpy as the dwarves or gnomes. As a human, you pretty much go with the flow of things.
As a mage, you like blowing things up. Your favorite bit of technology is anything that goes, 'boom'. You live for that huge front-end KAPOW - but, after the dust has settled, you'll find yourself searching for something else to explode.
