Alternative DPS gear set for a shout healer?
If you are weapon swapping consider Longbow as your second weapon. Take both Longbow traits and the Boon → %Damage one. Use shouts for Adrenaline and Faster Sigils in the Discipline tree. Shouting between weapon swaps will allow you to use a level 1 Hammer burst inside your level 3 Combo Field burst. You’ll stack plenty of might while pushing out a lot of AoE damage.
You could do fine if you swap to a dps weapon set. It won’t be amazing by all means, but if you’re already in a group with guardian(s) you’re usually better off running with more dps gear.
You could also try 20/20/0/30/0 if you want a middle-of-the-road build that can go high dps or somewhat tanky/support based on gear. I run that with either a zerker set + ruby orbs, or a soldier set with soldier runes, depending on if there is a guardian in the party or not.
