This is the build I usually roll with in PvE and sometimes WvW.

Using utility skills that give low cooldown toolbelt abilities, combined with the Static Discharge trait to generate some extra damage along with the rifle. Works pretty well for me in most cases.
My only question is, what would be the best Superior Runes to obtain to make this even better. There isn’t many conditions being used here accept the occasional bleed from Blunderbuss, but everything else is just straight up direct damage, so I’m thinking Power is the way to go.
My first guess on best rune would be Superior Runes of the Citadel, which gives both power and and bonuses to Fury. Perhaps someone else has a different idea though. Let me know? Thanks.
