Creating a LOTRO toon

I have had much greater difficulty than I first anticipated in choosing my character for LOTRO. I have been viewing the game through the lens of my large amount of experience in WoW.  However, class types in LOTRO appear to be a little more specialized and complex than in WoW.  While I knew that I wanted to be a melee combatant who could deal some damage, I ultimately became torn between the captain, the champion, and the guardian.  On the one hand, a champion seems to be the most heavily oriented towards dealing damage, but as a result, is also the least versatile.  Guardians appear to be good tanks, but they don't do as much damage, and it might be hard for them to solo as a result.  Captains can heal and fight, but they appear complicated to learn.  Regardless of class choice, I felt that a Dwarf would best suit any of these classes, as they are physically sturdy and capable of taking hits.  I ultimately settled on a champion, as I wanted to have a relatively simple character while I learned the game mechanics.  Hopefully, they will not be too different from WoW.

     I have some difficulty defining myself in relation to the framework that Bartle presents for MUD participants.I like to think that I shift around depending upon my mood, although I am usually not much intot he social aspect of MMOs.  I like to achieve and explore, however, at higher levels in WoW, I have found that running raids in not nearly as fun as fighting other players.  I'm not sure if this makes me a killer though, because I tend to do this in designated player versus player areas, in which everyone is a willing participant.
