Sounds like I ought to give Delve tanking a try.
My tank specs have been abandoned, and putting Brann back on DPS just makes more sense. He’s not the worst healing NPC (that title goes to Velen in the Mage Tower Tank Challenge) but a Hunter with a Healing spec just thematically bothers me.
If tanking through the Delves is faster than DPS, then… well, I’ve been doing this whole “delve” thing wrong.
