Well i played 2 NB builds and a templar, both redguards as that will be my race.
NB 1 was a dual wielding stealther
NB 2 was a 2 hand guerilla ganker
Templar was aldric spear line, lots of posts on every forums saying at level 50+ they are a bit hard to do anything with as opposed to other classes.
For PvP
The guerilla ganker was pretty fun you start off in stealth, and using a 2 hander I picked redguard because i needed the stam boost for the weapon skills. but from stealth you charge target, target woulld not see it coming and would be stunned. from there would go off with stam weapon skills until he is out of stun, hit shadow cloak, from shadow cloak i would hit the target with the stun from NB skill line (forget the name) and unleash stam skills and some magicka skills watch your meter. If target is still standing hit shadowcloak run away to regen or for distance to shoot with bow.
Never tried this with dual wield but instead of charge you would use (assault i believe)
