Everything you have said would be nice to have implemented but you did not give anything to start off of so here is a base
1st step in Creating this would be to make a maximum amount of 15 medics at a time
1st , 3rd Slot - Volunteer Medic
4th- 15th - (Whitelisted Paramedics)
Ranking
Volunteer Medic - (Unwhitelisted Restricted to the Medic Offroad and SUV) 1.5k per revive with a paycheck of 150$ every five minutes earning 1800$ per hour for newer players trying to earn some quick cash
Paramedic - ( Whitelisted, Can use all vehicles listed below as well as Acess to the Hummingbird helicopter, Van, Hatchback Sport) This is your everyday neighborhood paramedic meant for low-risk situations where civilians or cops need medical attention, Paramedics receive 1.5k per revive and a 500$ paycheck every five minutes earning 6000$ per hour
Combat Paramedic - ( Whitelisted, Acess to all the vehicles listed below as well as a Special Medic Plate Carrier along with access to a Medic Strider) Once this rank is achieved the Combat paramedic is able to save lives in the thick of combat and is even able to take shots and keep going earning 1.5k per revive but with an increased paycheck of 833$ per 5mins earning 10,000$ per hour
With everything Listed above many people is probably thinking well if this was implemented what would happen to the Civilian defibrillator
A few things that could be changed to balance everything out while still keeping the Civilian defibrillator
1st- Remove The 1.5k Reward that is given for Civs reviving other Civs
2nd - would be to Increase the timer after being revived by an unprofessional as well as making sway increase while the timer is counting down
All in all, I think that with the whitelisting of medics could add a great number of things for the community to enjoy feel free to criticize this idea as this is only to better the community of asylum as a whole
