What World of warcraft race should i be?

Well, seeing as Wrath of the Lich King introduced Dual Specs, I would advise rolling either a Druid or a Shaman seeing as either can fill the role of a melee cl, or a Spell Caster (magic as you've put it), both can be a healer and a druid can fill a tank role as well, so pick one and you can worry about the spec later on.
