My build for my survivalist type(Gatherer/Gecko and Brahmin Hunter/Armorer/sniper/etc) has proven very useful, I never really tagged outdoorsman itself, but I did up the stats needed to make traveling easier, such as strength and intelligence, took the skilled trait with 9 int, maxed AG out, while having no luck or Charisma, I have currently gathered 200 fibers, several pelts, several hides, lots of ore, and can build just about anything the character needs plus a few bonuses. Tagged Small guns, Science and Repair, within his first level he went from 60% SG, to 111% SG. Due to high int, he can heal himself easilly and only wait 7 minutes to do so again, 12 minutes for doctor.
Doctor Builds are easy, SG, Doc and FA, maxed int, Doctors are easy to play for new characters because they are useful to travel with, and would be an easy way to get some connections, possibly because I played a doctor, I was able to convince absolutely everyone a long while back(before we had this forum) to take down an Alt-warring, glitch abusing, race warring(Minigunned me for talking to a russian or some shit), PKer in Junktown, on my old survivalist build. Being a nice guy in general gives you the ability to incite an angry mob if someone has wronged you.
