Healer items drop all the time in Elite and NM
the problem is that healing in TSW takes a bit more to do than normal "healing" in other mmo.
Take healing for NM vs Elite. It is a world of difference. the popular build is Fist/Pistol (single target) and some go aoe (shelter build). In some fights it is really hard to heal people when everyone is running all over the place. In some fights the skill choices make a huge difference in healing (gear helps a lot too)
There is a huge learning curve and dexterity required to be a good healer.
