Guild Wars 2

Where should the Guardians Focus be?
Please advise.
When receiving a personal story reward, and these are the three choices…which is best?

It depends on what kind of Guardian you want to be.
Wanna be a “selfish” straight out damage dealer? Go for Power (at most), Precision and Condition Damage (your burning will inflict loads of damage)
If you want to become a support/healing guardian, go for Toughness and Healing Power.
