It's not unreasonable that many people don't understand the purpose of the FP system in this version of the game as it is indeed confusing. It was originally in the korean version to limit gameplay yes, but we are using it here in our version primarily to buy DFO Gold and combat the modern internet world that can easily hack every aspect of this game that was programmed a decade ago EXCEPT for the FP system as it's a serverside number.
It just so happens this already existing FP system, while originally for a different purpose, dramatically assists in controlling these automated bots as they cannot level endlessly 24/7 clearing dungeons within seconds. These bots will run out of FP in 10 minutes and have to wait till the next day, slowing them down SO exponentially that they can feasibly be dealt with. They cannot farm gold to sell until they are at the level cap, and they cannot reach the level cap for ~3 weeks instead of less than 1 day. Even if some somehow make it to level cap undetected, they will still be limited by FP and only be able to farm as much as a regular player in the end, rather than getting to spend 400 Blitz points on 100 accounts and DFO Gold every day.
Thank you very much for your dedication. This experience should help you recognize that you have a lot of true fans out here.
