Better experience if give: Violent tendencies (make your light combo useable again) Lone wolf (damned cant aim so lone wolf helps) Impatient (if you hate -40% speed) OR fearless (an some defence against oneshoting gun skavs)
Rookie mistake, never fight scav during looting phase unless you have bow. I learn this from veteran player and they taught me that melee is pathetic and want me to use brain and common sense over brute.
