My WHM co-healer in Void Ark didn't know anything else than Cure II and Medica II. You can imagine that their mana dropped faster than usual, but I wasn't in the mood of supporting bad healers, leaving me using all those Ewers I drew for either myself or Royal Road. But whatever, at some point in the game I learned to soloheal shit...
During the final boss, the bard told them that a WHM knows some more skills than just the two they were using, "Regen for example". And guess what, after this point they didn't use anything else than Regen.
