How about some defence for Doctors now that NW is out? In PvP areas, like Camelot, Doctors were always targeted first. It wasn't so bad then because of all the winding corridors and places you could escape to, but with NW being out in the open, you might as well put a coffin in our inventory before we even get there. Seriously, its like..
Slow target. Target tells everyone on the force that theres a doctor about and the name. 10 seconds later the doc is a big red blotch on the floor. Sometimes I think its pointless for me to even try PvPing at NW battles, I spend so little time there. Honestly, 95 percent of my time is spent travelling to the location, the other 5 is un-yalming, casting slow, then going to reclaim.
I don't know what can be done really, but try and figure something out. We're getting destroyed out there.
EDIT:
A quick idea. How about something like they had in the good old AD&D system for clerics. Because doctors are basically clerics. A Sanctuary type of nano. You're unable to be attacked, unless they resist the nano effects, but if YOU attack then the nano effects drop and you're open to be targeted by all. In AD&D, with Sanctuary up, you were able to do non-offensive things like heal or buff, but were unable to do anything offensive. Not sure if that would be too powerful in AO or not.
