I agree in Debt method. When it goes minus and they have no more ammo, they have to work their asses off selling cars to LSC and Simeon.
Additionally, Rockstar should take remove "wallet & bank" crap system and just make it like in SP. Every money goes directly to bank and it will be easier for the Debt system to go.
Most sensible thing I've read in ages
We don't want to stop people being free to have fun in free roam, just can't have it totally free and easy, or it just becomes a map wide permanent death match.
I feel the point of freeroam is that a little bit of everything is going on, and it's all random. Couple of guys robbing stores, someone chasing down a car for Simeon, other couple of guys chasing someone on the highway, someone having a shoot-out... all in the same shared space.
If there were no consequences, financial or otherwise, for just being perma-aggressive and a dick, it would just become utter chaos (and not the good kind).
I like how bombs etc are not cheap, and refilling with ammo can be quite expensive... it makes you more selective about using it, which helps things be a little more balanced and not just full on war 24/7. If you've earned (or bought) the money to be able to afford to go on extravagant killing/destruction sprees.... then go ahead and ENJOY!
