Ok well I'm a Gnome mage and i really like it. They get an extra intellect boost which is good for magi. Also if you're more of a horde person do BE. Mana tap really helps you can silence them and get mana for it too. For pvp reasons (say if you're gonna twink him) then I'd have to say humans. They have an extra stealth detection boost which can help kill those OP rogue twinks (as if rogues aren't strong enough) Hope this helps =)
