They need to make the game more server-side oriented and use the dynamic content system to prevent most of these hacks and end free-for-all events like White Tree Hill from the game and instead use player-direct events like the Halloween event.

Nexon knew this event would end up with a ton of hackers going berserk and hogging everything and they still released the event, and their failure to shutdown one of biggest know hacker communities proves they have no idea how to handle GMS anymore.

You're asking too much of them.

Though, really, there's been a pretty big increase in hacking since Big Bang was implemented, at least in Bera. I could name a handful of maps right now that have been riddled with hackers since Big Bang.
