Bullshit. Modded cars - complete imbalance. When you dump a couple dozen bullets from a sniper rifle into the driver's windshield and side window, and he doesn't give a damn... well, what's there to talk about. If you donate - you're a god, if you just play - suck it... because the guy in the G-Wagon will just stupidly drive in circles to figure out where you're shooting, but be completely safe.
Everything is done well of course, I won't argue! BUT! Balance is completely absent. I think, so that the kiddies don't suffer and just fully satisfy their ego, you should start selling WH, AIM, and TP - they'll buy it, don't worry, and the balance in the current reality will break just minimally, but the guys with money will be more than happy!
