Barbs are about stealth. So you might wanna go conq or guardian as those are the main fighter classes.
You can level up to 20 in no time at all so you might as well as level up and then start another character to see which you like best. If you can get them all to the 15-20 range or atleast a few of them you can then start a new one with your friend and when he gets to 15-20 just swap to which ever class you are having the most fun at.
I am a barb right now, bez stance due to the 2nd stuns and cc abilities.
