Healers less so than Tanks, and frankly I think we dramatically overestimate what we need for a lot of these fights.
I get everyone just zergs Maulgar now but there’s absolutely no need for a dedicated Tank spec for any of the adds. Blindeye hits so anemically that I’m pretty sure I could hold him and survive in Cat Form, and only Olm needs someone on him at the start until fel hounds can get into play.
