I believe Chrome shouldn't be able to be taken from a corpse by someone who isn't a trained professional. The rotting doesn't matter, as you can just bring a cooler with you in the fight, then stick them in. A roughly 10k investment to completely circumnavigate needing a doctor. You have 'ripper doc' as a archetype for the game but they literally can't do a large portion of their jobs because of the portable fridge. We've all seen in the past how people are literally just treated as walking ATMs for their chrome without any cyberdocs needed. High level combat ue characters especially have a field day with this. It's literally profitable to kill their enemies all because of a portable fridge.
Decker technology: I feel like Deckers especially would be the kind of people to completely cover themselves in cool shinies. They always are in every other cyberpunk setting for the most part. A fun idea I thought of is the more PDS you have the better you are at hacking. You interface better with the computers. This'd make a REALLY fun dynamic I feel. I'm sure the specifics of 'x cyberware that hacks you with Y' are obvious so I'll leave that out. Oh, a holographic displaying one would be cool. I know everyone here wants to hack like Sombra from overwatch.
Finally, one thing that I feel might be missed out: Fashion. In an age of technology, you'd think wearable tech would be really. Cool. Sleek etched ivory limbs, really beautiful looking cybernetics for the more gauche fashion users. This is probably the biggest want for me. The idea that technology is ONLY for its uses, and not its looks is obviously a false one, just look at the new designs phones/laptops etc get every year. My own PC has a glass case with fancy lighting and all that. Pushing the limits of humanity with technology, including, ESPECIALLY the human image is all what Cyberpunk is about!
