-My idea was to start you off outside TVH, like a block away. I'd prefer not to split you guys up, one cuz you're not an "army", and secondly because you're safer in a group.
-For flavor reasons, be careful with the amateurish label. Remember, shadowrunners are professionals, so just because a shadowrunner is able to gain access to something doesn't mean it was amateurishly hidden. It's the same with the whole hacking dilemma I encounter with my table-top GM. He feels that since there exists game rules that make it possible for a Hacker to hack into people's comm's, hosts, etc., he believes no-one in his campaign world ever would put anything important on a comm or online. He feels that the security risk posed by hackers has created a 6th world in his mind where no-one puts anything of value online because that would just be stupid and amateurish and a total security risk. Aside from totally nerfing an already weak archetype like the decker, it also makes no sense then why there even is a matrix to begin with and why would it pervade all aspects of life. So my take on the matrix is that a PC decker/technomancer is quite a special individual that poses quite a unique threat which even the best of systems have trouble subverting. Most system's, even rating 1 are really quite secure when you compare it to regular people and regular corporate activity. Everyone actually puts very sensitive data online because they have to use it every day and for the most part they never have any problems. It's the same way today, all these companies have all this credit card information and they make way more money by having it online than the money they lose when every few months it gets hacked. That doesn't make the companies amateurs, it's just the reality of how incredibly good hackers are. So I feel it's the same way for every archetype; don't compare yourself to average everyday world. You guys are professionals and the people you are fighting against are very professional as well, we just need some way of rolling dice in order to figure out who wins.
-You're on the right track, just a few more data-searches might point you in a more specific direction and save you some trouble. You just gotta search for the right things.
