I agree with the overall premise. Attributes are kinda dumb. SP should just accrue at a steady rate.
As it stands, you can Remap and Implant for maximum gain on Mining skills or whatever. And then use an Extractor to suck up all that SP and Inject it into Gunnery or something instead. If your Attributes are leaning away from optimal Gunnery training, then why can you Inject the same amount of SP as anything else? Shouldn’t the Injection be diminished b/c your Attributes aren’t optimal for that skillset?
Or…
Just get rid of the idea of Attributes, and make everything train at the same rate. Then Injection makes perfect sense, b/c it’s just adding more SP quickly. And then nobody needs to bother with Remaps or Attribute modifier implants. You can still have Snakes and Slaves and whatever else, but they won’t alter your Charisma or Perception.
It’s time we stop pretending that we’re playing space D&D, and just focus on shooting stuff.
