why would cops have nlr...even 5 mins... its to simulate backup... you gun down all the cops of a town... the cops of the neighboring town, county sheriff, state police, etc. isnt going to say, oh well they all dead, not our problem...no they a re going to double time their ass to the situation to arrest the guys who killed their brothers in arms...
Fighting cops is easy AF as is.... wipe the first group, then run....if you cant get away, get to the nearest red zone, wipe the wave, then bounce between waves...if that still dont work.... go to rebel...if there isnt a Sgt+ on (which is most the time) they can only go in of 1st wave and 1st wave backup...(only if they follow you in)
know the rules and know when to run... nerfing cops to be fair for small unorganized groups will render them useless for larger organized groups... get better and grow your group and stop bitching... learn different strategies for different personnel you have on... also know your group... be real with yourself... know your skill and don't get pissed when others are better then you..
