Guardian stats/weapon sets
Karma is as abundant as air, and as useless as the Kardashians.
Greatsword is power oriented with slight benefit from precision. Sword is Precision oriented and adding a torch just adds slightly more dps to wielding a sword.
If you want to go with this build push Zeal for dmg and Radiance for increased crit chance.
Depending which you want to use more use your traits accordingly, for Greatsword 30 in zeal. for sword/torch go 30 radiance.
Note that this build is mainly focused on dishing out dps. I would suggest dumping the rest of your trait points into valor to at least increase your base armor when fighting in melee range.
As for armor stats it depends what you want to play more, GS or S/T power/precision with +crit stats and such.
Hope this helps a bit.
