i agree, in a way, i see what you mean. at the same time though, there's nothing stopping a street sam from using recon drones for legwork, being stealthy and using tech to listen in on conversations, doing data searches etc.
being THE face of the group is a big responsibility as it determines peoples pay, how successful your social side of the legwork goes and such. its not something i'd want to do on my very first run or until i know how you're actually supposed to play that character.
learning a set of rules in slightly more detail than for other chars is a bit different to learning all of the social rules on top of the combat rules, as well as everything else.
baptism of fire works for some people though :-)
