What can Nexon do to prevent hacks or make the game less vulnerable to exploitation?

Completely agree. But I don't think it has turned out cost-effective or whatever horsepomegranate excuses they blurt out. What do you think they should do or should've done?

It's at a point where it's very obvious that there needs to be a complete code overhaul, which is completely out of the question. It costs too much money, time, man-power, and effort for something like that.

The only thing we can hope for is that MS2, if it ever comes, will be coded more appropriately. We can hope that's why its taking them so long. The more hacks people come out with for MS1 is more crap they can look into preventing in the base code for MS2.
