Healers are the same way they've been since the start

Primary role: clear the encounter by damaging the boss and keeping the party alive through unavoidable damage
Secondary role: heal the party through avoidable damage and res the dead.

You cannot clear any msq duty without doing dps. Nor can you do it as a healer if you let your comrades kick the bucket. SE won't give us the echo so we have to heal ourselves.
