I posted this on the Commando forums but wanted to get some thoughts from the general healing community....
Although I might be mistaken, it seems that as the armor for the healer gets better, their arsenal of tools get smaller (see Priest vs. Holy Paladin in WOW or Sage Healer vs. Trooper Medic here).
However, as somoene with a level 45 sage healer and a level 30 medic, I think Sage Healers might have better "armor" in terms of being able to cast Rejuvenation and Force Shield on themselves before going into battle or as soon as they get attacked. Force Shield absorbs a lot of damage and Rejuvenation has a nice duration (specially if you put some talent points into it). In addition, we can always use Healing Trance if we have accidentally pulled more than one mob group while Qyzen kills the baddies. Instant cast is very nice on Healing Trance...
So it seems that the one advantage that Trooper Medics had - armor - is really not that much of an advantage. In return, we also have a smaller arsenal of tools and the tools we have, don't really compare favorably to what sages have.
Sages, Medic and Sawbones out there - what are your thoughts?
