Get close to the creature, and whack it. Use special attacks. Unlike a marksman, you won't be kneeling or prone. Consider getting some armor later on, it helps. Tatics are just as important, and the more special moves you get, the more effective you will be. Eventually, if you master an advanced melee profession, you will be very powerful. Till then, you gotta watch out, and keep an eye on your health when you fight.
