So hold on, you're going to justify with control rigs and RCCs? Let me give my brain a moment to process this. The control rig. The piece that requires a sentence or three. The RCC. The piece that is basically "This is a fancy remote control that provides you with a control network for your drones." Basic functionality, sure. Cool, I'm good with that - needed to be done, was entirely too easy for the groups decker to also dabble in decking before. Don't justify a scarcity of information with it.
I get that I need to be patient, I really do. Would it have killed them to post something along the lines of "btw, you can increase armor to X value" to go with the gun drone mounts? Or "btw, here is a pilot/sensor upgrade price list. Don't get carried away, there'll be more in <insert title name here.>" I'm not asking for a dozen fragging pages, I'm asking that my rigger have the simple pleasure of doing more than mounting a giant fragging gun on his bloody drone.
Personally, I'm content with the '500 pages? yeah, we need to stop.' I can leave it at that, but don't use the things you've put in as "this is what you need to have basic functionality in your job' as a justification to anything. Truth of the matter is, you don't have to, and the one you gave there... well, no way I can say this easily, but that one is going to frustrate people.
That said, I'm working on extrapolating a few of the modification rules over to 5E as a sort of stopgap. Some of the things probably won't work anymore, others however, should, with reasonable effectiveness.
