Sylvari Guardian is a very interesting choice, as they're not a combination I'd have thought to go with. Of course it doesn't affect stats at all obviously but just in terms of the theme I guess. I'm intrigued by necromancers in every race - I suppose I love the aesthetic, and playing as a AoE condition dealer has been quite fun too. Charr thief is another class that interests me, but I'm playing it already and I'm not too good at it I must admit. I love the idea of the Sylvari Nightmare Court so I really hope that becomes a playable story line and I can play that as either a Mesmer or Necromancer. That'd really make my day - though, looking at how all the other playable classes so far have had an evil NPC version (Flame Legion, Bandits and Sons of Svanir) so I would bet money that Nightmare Court is the Sylvari's evil NPC twin.
