...why is that stupid? It's the common sense way to build, and has been for a long time Xenon, so I'm very confused as to why your saying that.
Read some cyberpunk influenced literature and you will notice that basically only physically strong archetypes, such as street samurais or retired war veterans, have chromed arms... while weaker archetypes, like deckers, rarely have a chromed arm of death to make them god-like gunslingers. It is simply very cyberpunk-ish for a street samurai to have cybernetic limbs. It fits the overall theme of the setting.
But as rules are currently written in Shadowrun it doesn't. Instead it make perfect sense from a min-max char gen point of view to get a single high agility arm as a decker but not to replace your arms with chrome if you are a street samurai.
As rules are currently written in Shadowrun you get penalized for getting cyberlimbs if you are a physically strong metatype such as orc or troll street samurai or an agile metatype such as an elf gunslinger. In Shadowrun a street samurai with high physical attributes will potentially even limit himself to lower maximum attribute ratings if he replace his arms with chrome compared to if he would just augment his natural body.
I personally don't think Shadowrun cyberlimb rules should penalize physically strong metatypes such as dwarf, orc or troll or agile metatypes such as an elf. I don't think Shadowrun cyberlimb rules should limit the potential of a physically strong street samurai or an agile gunslinger. I don't think Shadowrun cyberlimb rules should promote physically weak archetypes such as a human decker or face getting a cyberarm of death.
I have some great house rules to change this that I posted on this very board years ago. Might try to dig them up that post at some point...
In the meanwhile my physad decker also happen to be a
very skilled gunslinger thanks to the cyberam of death (which also fit his cyberdeck) and improved pistol power. And since his meat space initiative is sky high from Improved Reflexes he have no issues doing his hacking from AR, which mean he is immune to biofeedback and dump shock and that he can establish direct connections to a slaved devices or even entering hostile hosts in with his matrix persona in AR mode to get direct connection to all cameras, weapon turrets, doors, drones, elevators, etc. that are part of the WAN
while being together with the on-site Shadowrun team (shooting at guards or whatnot). It is a really fun character to play. It get a lot of scene time. Thank you cyberarm of death.
