I think they are good as they are. I don't use Physick on my SMN unless I am trying to pick up for a healer being down and trying to keep the tank alive as long as possible. As with everyone though the sustain being removed is curious. Admittedly, I do not really use Sustain that much and throw away my pets because I attribute it to not positioning my egi as best as I can.
I would say to leave it alone from what we know. I wouldn't want any more expectation of healing on my SMN, as for RDM the healing is meant to be one off situations as best as I understand it.
