If there was a milestone events on this server chasing by cops would be more enjoyable and more rewarding
You mean like the events organised by the NFSSA Events Hub?
No, the milestones challenges that existed on nfs mw, Avoid roadblocks, spike strips, trade paint with cops, earn X amount of bounty, disable X cops etc etc that were necessary to challenge the blacklist boss.
I think it was planned and then got canceled. Idk, maybe could make it if reworked.
