Nice pic. I still think they should include the option to switch between first and third person as it would open up the game to a lot more people, plus its always nice to be able to see what your character looks like (and in combat).
Its a tough one, personally in a PvP MMO I think first person only makes sense. You shouldnt be able to see people creeping up behind you, third person would allow that. The lack of third person I feel increases the tension and also increases the potential tactics which can be used.
