First thing is the 2 runes that are missing from here are MAJOR runes of sanctuary, The tip i will give is as a Gaurdian is to learn every weapon, As you learn the game you begin to learn what sets work best where.
Actual stats on my toon are without buffs,foods etc:
Crit C & Crit dmg 25% at 74%
Boon Duration +50%
Healing power 350
This is the lazy mans build to taking your guardian every where, Weather that be FOTM,WvW,Dungeons or chilling doing some map completion.Use Chocolate Omnomberry creams to boost your Boon duration upto +70% this allows increase stacking of might and keeps Protection up(-33% dmg is great for any dps type build)
Weapons use PVT(power,toughness,Vitality) along with Back piece and amulet everything else is berserker's.
Along with you often changing weapons to suit your location you will also find yourself needing to adjust your traits. Again this is just going to be one of those thing you will need to familiarise yourself with.
I believe this is all you need to know the rest of how you play this build is upto you, ENJOY,
