I'm curious about what other Guardians slot onto their Utility bars for specific encounters in T4. I play Core Guard (Zeal / Radiance /Virtues), and as standard I run:
Litany of Wrath, Sword of Justice, "Retreat", Bane Signet, and Signet of Courage (swap to "Feel My Wrath" if no Chrono)
If I'm in a fight where I need more CC I'll drop "Retreat" for Hammer of Wisdom. Lately I've been trying to get the hang of Shield of the Avenger, but I don't think I'm using it correctly outside of Nightmare.
But what specific boss fights in T4 do you swap in a niche utility skill for, and why?
