The moment I read the pimps changed stealth i knew that they had nerved it to the ground.
Problem was, they also changed farming into the old grind days. So I decided that in our multiplayer game I would avoid fortitude untill we start with a mod, that doesn't use that nonsense. So I had to adept. The most interesting change for me, was to perk and wear heavy armor. Funny thing it worked far better than expected.
So I would say a AGI + STR build is they way to go. Just don't waste any points into stealth and youre good.
