True enough, but I just keep giving them "classtime" at the black vine every day, and many of my healers are Master Doctors by 34, so it's not really that long. One thing about having several Adepts and several trainee Doctors is that if someone becomes ill, they all rush to the place and mill about, and the poor SICK individual stands there "Waiting for someone." You still have to drag somebody to the sick villager to heal them.
