This is not finalized, but nonetheless some findings and thoughts from DM Evenstar regarding Druids within the Dragonlance setting:
In "The Soulforge" by Margaret Weiss - One of the highmages refers to a local cult's healing abilities as being "no different from what the Druids have been doing for years."
Also, in the PnP Modules, the PCs encounter a druid "Weyland" who has been driven insane and put to sleep for 100 years by the Silvanesti elves.
That said, discretion of magical abilities would be the norm: They would heal, as it suits them, but I doubt, that they would change into a bear in full view of city dwellers... That is that they would certainly NOT do it in front of non-druids, generall. But WOULD, out of view.
