Right, firstly, the Encode DNA Sequence Doc nano line makes absolutely no sense whatsoever. Docs can (for some odd reason) encode their team into digital format at level 80, but can't cancel a poison. IMNSHO, this should be a skill limited as much as possible to Fixers. Instead, half the profs in the game have some kind of grid nano.
Instead, I would put in something like a EMT/Emergency Response line.
Teleport YOU (and only you, the Doc) to a team member. Na cost of 1/2 the average pool at that level, cast time 15 seconds at level 80, 10 seconds at level 120, 5 seconds at level 160. High interrupt chance, so it can't easily be used to escape from combat. Or just add the "Can't be in combat" req.
Scenario: In a mission, the Atrox Enforcer makes a wrong turn, perhaps seeing a shiny object, and stumbles into a room of 2 red mobs. The Doc, following closely behind the rest of the team several rooms away, hears the confused calls for help over the team radio link, selects the unfortunate 'trox, and throws out the emergency medical response. Blip, 10 seconds later, the Doc is next to the Enforcer, healing its meaty ass. About 20 seconds later the rest of the team gets there and finishes off the mobs. The Atrox /prostrates the Doc and gives her lots and lots of money and items.
OK, maybe that last bit was idealized, but I think you see the point.
