All4BigGuns, you have a lot of hatred for this new system, but you also don't seem to understand how it works.
There's a lot more steps involved than just saying, "I'm going to shut down that guy's gun, commlink, whatever." Especially if the enemy has a decker that is guarding his gear. Additionally, you keep mentioning that the decker can be "some place they can't be seen." That's just wrong. The device is almost certainly running silently, and the decker is going to want to be within 100m to account for noise. Other people have already gone on about the steps necessary for the decker to shut things down, and there are a lot of methods that GMs can use to further protect their NPCs. Also, this works both ways, so the team's decker needs to be on his toes to account for any shenanigans that the NPCs might try to pull.
