I'm surprised at just what everyone in City of XXXXXX denotes as healing....
Universally, healing is in essence the opposite of damage. This does not always mean it needs to take effect AFTER damage has been done.
As I consider myself a Devout "Healer" with at least one of my characters in any MMO I play:
In my experience, I would praise my tanks who actually geared up properly, because in essence, they helped heal themselves by absorbing damage before it became visible. This also applies to buffs, and de-buffs. What ever in any way minimizes damage and helps to achieve the end goal of sustaining the team is considerably an act of healing. Just because it's indirect, doesn't discount it.
My first 50 was an Emp/Psy, I re-rolled it because I felt utterly useless in a better bilt team, save for my MoSTF, I didn't actually have much else to do than CM everyone rapidly, Fort the Squishy Figters, Teleport people who slacked, Cast Vengance on our inevitable moron, and provide Leaderhsip to everyone.
This exact toon was Re-Rolled as an Mind/Empathy Controller, and fulfills ALL of theese rolls and MORE, has also been the sole direct healer in an MoSTF, and save for Leaderhsip just not beign as strong, the Toon is now FAR more effective in ALL aspects of the game for me.
I as an Empath/Pain Domination Player understand fully what being a Direct healer means, and I know how to be more than just an idle mass while taking on this role.
However my point is that Healers ARE needed, but close minded people don't understand what constitutes HEALING. In CoX Healing =/= Empathy/Pain Domination/Thermal.
I do on othe other hand know for a fact that there are plenty of situations where a direct healer is required. Just because it's part of the game that "YOU" don't partake in often or ever does not mean you have the right to be angry at those who know what they need.
