A couple of issues I have... Buying property is pretty pointless for the most part. It sucks you can't actually go in the businesses you buy and the missions are a joke. Making a beer run for the bar you buy? Whatever. Like I'm gonna drive my Adder down the road and leave it to get in a slow ass box truck and drive a boring ass mission to the bar and my adder gets thrown into the impound (if it doesnt glitch-vanish).
They do need to tone down the wanted levels. It is way too easy to get a 1 star and 1 star turns into 2 stars to easily. It's like if you get rammed by a cop car during a 1 star chase you get 2 stars.
Also, they police helos spawn to fast, there is really no point in shooting one down since another shows up almost instantly.
I dont mind the cops being able to shoot you down rather quickly, I just wish it took a bit more rampaging to get them to come after you. I bumped into a guy on the street and he challenged me to a fight, i punched him, pretty much in self defense, and got a 1 star. That's over kill in a game like this.
