Nexon can not patch hacks FOREVER! And definitely not for 6-10 months. There will always be that desperate coder that needs to proove this, and will find the bypass easily.
Vac2 was said to be un-bypassable, look at it now, Aimbots and wallhacks everywhere for Vac2 supported games. So that isn't true.
Hacks are most likely about 1-3 weeks away depending on how hard it will be to Bypass HackShield after so long.
