The other option is to dual wield ie, 2 one handed weapons in each hand. It really depends on your own personal preference. In general if you look at your talent tree and want to go down the Arms route then a 2 handed weapon is preferred. If you fancy the Fury tree then people will usually dual wield. Of course theres no official limit, play with what u like but they are basically the choices
I believe you get the dual wield ability at lvl 10 (I may be wrong..it's been a while

)
