I am assuming this is a PvE build since you have no escapes. I don't think the lack of the aoe is that big a problem, but you are giving up Survival Training and wasting alot of points that don't seem useful especially if this is a PvE build just to get to Combat Stims. IMO Combat Stims it will not be worth all the points it takes you to get there. But if energy ends up being a big problem and Combat Stims alleviates it well then maybe its a good choice.
I would only choose a build like this if later on I found I was really hurting for energy, but it would definitely not be my first build to go for. I'd suggest trying to play the game without the combat stim talent first since it is a bit of a crutch, and you waste points that could be used for example on Survival Training. If you are really unable to manage your energy without it then go for it later. But I would be very suprised if Combat Stims were required as a medic since it really removes alot of other important medic related talents from the table. IMO you are sacrificing better heals for an energy crutch you should not need.
If this is a PvP build, well its not very good (no escape talents).
