Your argument is so Invalid. One of the major reasons why medics are a thing is to help civs AND cops. Yes they have discounts on vehicles, yes you make 17.5K per revive, it isnt that difficult to make money on Medic. Cops have NO NLR and can just respawn at the nearest HQ and go back to fighting civs or whatever they were doing before then, Civs have NLR so here is a good example: Major Pain one of the BIGGEST Kavala Scats on Olympus always betting in Kavala. If there are no medics on and he dies then he will have NLR he has to wait 15 minutes before he can go back there... OR a medic can go and revive him in that 15 minute time window. Medics aren't helping themselves like cops are they are helping others 99% of the time. Medics also have NLR under several different reasons.
Cops never see a point in Medics or don't care about Medics because they don't need medics. If you are a EMT or Basic Paramedic that is the prime time to make money as a medic, they mainly stay in cities and help out anyone that needs help, Adv.,S&R, and Sr. Medics all are usually flying around from city to city or city to the middle of bum fuck no where taking time to make money. They have to usually get the people further away from cities which makes your time to make money a lot less money.
Medics are benefiting people in many ways. Cops don't benefit anyone but themselves usually(not saying APD is useless). If APD had discounts on vehicles they would have tons of vehicles meanwhile on medic you are usually always in a vehicle. Also most civs aren't fighting medics so they don't titan or destroy vehicles as much usually its just a mess up that causes Medics to lose insurance.
Most cops don't give 2 shits about medics if they press their panic button, or even when they had the medic/cop channel Medics are actually valuable to civs and a bunch of cops fail to see that. Without medics, civs would be a lot more poor and there wouldn't be nearly as many rebels to fight, or runs to bust due to arma bugs, rdm, just fights, or even more. Medics keep civs from losing a 150K+ loadout if they really need to request and many cops don't actually realize this. Also this is proof cops don't care, The first day after the cop and medic channel got removed on Jordan540's stream u can clearly tell Mako cares a lot about medics https://clips.twitch.tv/AgileGorgeousSpaghettiYee and ever since this channel got removed the likeliness of cops actually showing up to a medic pressing his/her panic button has become a lot slimmer. Yes the cop and medic channel was aids but just showing how cops don't realize the value of medics to Civs
Seperate from that:
Fighting cops in Warzone would be fun like last night BFO fought @Dante and a bunch of PO's we fought them for 3 waves then we stopped, it was fun and it would be really cool if we got some kind of reward for fighting them at the least. Even tho we were trying to get Dante to come it would still be cool to fight cops if other gangs are not on
