Less the difficulty and UP the ammount of police on you.
otherwise than that, that's just a suggestion. I think it's fine. In fact, they need tanks like all the old school gta's. Maybe they should add another star so that the people with tanks gets killed by other the police with tanks
there is a great ammount of police officers already.. enter an ammunation, start a shootout with them.. it is impossible to leave the store to a getaway car.. there is an infinite number of cops. when you kill 1, 5 already spawned..
they should put more police departments in game, and patrolling vehicles, and the police ONLY chase you from wherever they are, or dispatch from the PDs. not just spawn nearby you.
