That's pretty much my rotation: Force Armour, HoT, Deliverance, Healing Trance, HoT. But I'm wondering whether the bubble has any viability at all in hardmodes, especially on bosses that hit so hard that the bubble can't even absorb a single hit. Wouldn't the gcd be used better on just casting heals.
You've clearly never played a disc priest in wow. its an insta cast 2.5k preheal, talented it has no CD. Some times I only shield.
