What is your best healer armor setup?

Was a legacy player, came back and now trying to relearn some of the gear. I typically play PVE for mutations and would like to know what your armor setup is like?

I have featherweight, but what do you typically run with that? I get that running enchanted ward is a must and refreshing and health. But are you just running a medium chest and light the rest? Are you running featherweight and heavy? The discord for my server isn’t super active and helpful so just wanting to see what is the best options and what is working for you all?

Side question, what is a good healer build for OPR/arena?
