Medic Archive

As a combat professional, if I was interested in picking up some medic skills to help improve my soloability, which trees or skills would you recommend that I pick up first. Lets say that I only have enuff skills points to pick up say 4-6 boxes in the medic line, which ones would you recommend and why, or which skill trees do you feel are the most important. Don't really know too much about healing. Thanks alot for any help and tips.

Pharm cuz it grants access to higher packs...

followed by FA for more effective heals
