Since my Guardian is going to hit 80 soon, I decided to try and play with a potential build. This is what I came up with:

No idea how it would actually work in practice, but I think it looks pretty solid for roaming with a small party/solo. Decent amount of Vitality and Armor, and the Healing Power should keep me alive pretty well.
Comments and criticism would be appreciated.
