In case you haven't noticed, the combat arms community is dying. So is nexon. You don't own a gaming company so you wouldn't understand what they have to do to keep the game alive. Now, I'm not saying I own nexon and that I know everything about gaming companies, I don't. I just want you to understand that other then overpowered nx items, nexon has no other way to make money to keep the game going. If you want to still play it free, you'll have to either live with it or buy your own NX. If you don't like it, go play another game that doesn't piss you off. But I'll have to tell you no matter what you play, you'll always get mad sometimes and cry "(name here) sux ballx (company name here) is bullshit (weapon or w/e name here) is overpowered!!!!!!!!"
In other words, no matter what game you play, no matter if it's free or not, there are always going to be weapons that are overpowered, hacks that can't be patched, and glitches that can't be fixed. If you want to play computer games of any kind, you're going to have to deal with bullshit one time or another.
In even simpler words, no matter where you go or what you do in life, you're always going to have to deal with bullshit.
I feel sorry for you for the fact that you don't understand that concept.
