Guild Wars 2

Hey guys, i currently on a Rifle / Grenade build, with full alchemy traits

Im looking for Runes, suitable for wvw/dungeon/farm (in this order)

Traits 20/20/0/30/0

Armor : Berserker (exotic craft) (power/precision/critDmg)

Ive been using Scholar and Eagle Runes (glass cannon)

So what runes are suitable ?

Thank you for your time

Any suggestions at all ?

i am willing to drop some precision/power from current for a bit more “tanky style” runes, but not sure what to aim for :/
