Good Natured increases First Aid, Doctor, Barter, and Speech. Since Speech is useless for low intelligence characters because most character won't even want to talk to you, I'm wondering if Good Natured is still of use for stupid characters or if it should substituted for another.

Now I know that Gifted should not be taken if stupid. Small Frame is planned to be taken by all of my low intelligence characters. One Hander is for those using pistols. Fast Shot for quickshot and burst fire builds, Jinxed for Jinxed. Now I'm still trying to decide what's a good second trait for Snipers and Hand To Hand characters. Should I still take Good Natured together with Small Frame, or should I take something else? What's a good replacement for low intelligence characters if Good Natured shouldn't be taken?
