iZone atm is really unbalanced. The point of Zone is PKing and you make the most money off of it right?
How do you get gralats? You need to PK. But, you can't PK correctly/efficiently without getting a good gun because everyone with an OP gun kills you if you have an inferior gun.
So that leaves you stuck between a rock and a hard place. They only way is to do missions, because no one can kill you then. But you don't get any gralats from missions, so you can't get money without PKing. But how do you PK without being raped? Wth a good gun. The only way out is to buy gralat packs. And unfortunately, I'm not going to bust my parents' credit rating for an online game.
tl;dr: Zone is stuck in a perpetual loop where the only way to gain money is to PK, but you can't do it well unless youhave a good gun. And to get a good gun, you have to PK for the gralats. But you keep getting killed if you have an inferior gun. Therefore, the only logical solution is to buy gralat packs since missions give you 0.
