xD I would think this would be pld -.- (shield/sword whichever) i mean, why would a whm sacrifice, i mean i do all the time, but isnt it the plds job to die protecting the rest of the team? xD
The tanks job and the healers job in a pt is basically the same, protect the lives of the pt members and keep them alive. A healer (whm) can sacrifice their life for the pt keeping people alive just as easily as a pld could. I think sacrifice is very fitting a whm.
