Actually, make the printers more like boosters than can be upgraded more and more to provide side income on top of your normal pay
This wouldn't work because of voice chat, and because randomized jobs are anti-fun
I'd say make it so that it takes a few minutes to respawn, and then once time passes you respawn in a hospital
This kills a lot of features within DarkRP and cuts down on all the fun shit (fortresses, walls, ect)
Some things I would do:
Certain things are based on skills, which determine what abilities you have and are raised by your job type. Specifically, starting off with low gun damage and low gun control would discourage RDM and more encourage playing to get better. When you get killed, your stats drop and you loose your job. However, get things done correctly and you get major stat boosts
Also, if you get arrested, you have certain prohibitions when you get out. If you were arrested for murder, you can no longer bare weapons. If you were arrested for stealing, you have a temp ban on earning currency.
CP officers get money every time they make an arrest. This encourages officers to enforce laws. If the police become corrupt and arrest innocent people, the objective of overthrowing the CP comes into play.
Game detects when you have committed a murder, stole from someone, or various other crime.
Jobs have more importance. Medics provide healthcare and can cause dead people to respawn faster, cooks can decrease hunger, drug dealers give stat boosts, ect
More variety in classes
Make it so that props cost money and can be sold by either NPCs or players, and that cheap props are weak but strong props are expensive
and a better construction system
