Turns out to be pretty easy on story mode. Just tried it out of boredom, with no problems. We one shot everything and no deaths.
Anyone done this on Hard? My instincts tell me Tanks onwards would be too difficult, but this may just be me getting lazy and unimaginative given how easy healing has been since launch.
The tanks wouldn't be the problem. Toth and Zorn, Vorgath, and Kephess would be the problems. You only need 1 healer on the tanks, because firebrand hits like a wet noodle even for wet noodle standards.
