I agree with what Kyet has written, I like what the wiki states about 'making a choice' as with who to give implants. Implants are reasonably powerful, I don't think they should be given any more than they have now.
My only complaint with the role is thus: You can spend all your implants at roundstart, only to have a Magistrate or other very important person to arrive, and not have an implant for them. This isn't necessarily anything that can be fixed to my knowledge, though. This is similar to the SSD/cloned complaint. I have no idea how to fix this, or if it needs to be fixed.
Overall, I like the blueshield job, it's one I find myself playing often, and think it's one of the best and most balanced roles in the game.
