"Balance" is for shifty fantasy games that have people doing epic crap for the sake of being epic. Shadowrun is set in a highly realistic setting (the real world). While magic gives it a fantasy character, everyone and everything in the setting acts and reacts realistically and plausibly. There are no "Sons of the Lost King running around with magic swords taking over kingdoms because everyone expects him to lead them to victory," because that is asinine. It is a high fantasy trope that can only work in fiction, where the author has control over the story.
Ever shout at a movie because the characters did something retarded for the sake of moving the story forward? That doesn't mesh well in a world where people die from doing something dumb. Shadowrun does have a few people doing dumb things like that, and they are dead or soon to be. You don't survive without learning, you don't get paid without thinking.
Remember that there are consequences to every action. Even if it is only a free action to drop your signal and thus boot the hacker, you just dropped the rest of your team, too. And when you power it up, your team gets distracted by you logging back into their network (assuming they have theirs on active) and the hacker gets a new chance to grab you. You, on the other hand, have to reaquire all the signals you just dumped. That can be a problem if you were trying to hack anything at all (which is likely).
"Game Balance" is, IMO, often the lazy way to judge an action (even in those wacky fantasy games). The "realistic" way often opens up options that the player hadn't considered previously, and wouldn't have if they had taken the "balanced" way out. Don't fall prey to it, you will be rewarded for clever thinking in the long run (and possibly the short run, too).
