Guardian Trait Confusion
What are using as utility skills (signets? meditations? shouts? spirit weapons?) ? Which level are you currently?
With one handed weapons I would go for the Radiance tree first and aim for something like that.

If you play solo you should give the focus a try. I find it better overall than the shield :-)
Sword mainly benefits from Radiance;
Blind Exposure: Applying blind also applies vulnerability.
Powerful Blades: Sword and spear damage is increased by 5%.
Right-Hand Strength: Critical-hit chance with one-handed weapons is increased by 15%.
Shield only has one in Valor, but it’s pretty decent if you use it a lot.
Honorable Shield: Gain +90 Toughness when wielding a shield and reduce the cooldown on Shield skills by 20%.
Heavens Rage
Probably pick up Radiance, as said. But it’s really hard to make a bad build in this game, unless you use the Zeal-line.
