But you can definitely keep the poor, poor. So why are adena drops so damn low in this game?

[TDxDan 34]

to keep lowbie Bot Armys away. if you had decent amount of adena income. Bot Armys of 10 000s would return like it was before. Spots would be swamped over. 
Even back in the Day  Pay to Play model would not keep Bots away cause they made more Cash than it did cost to pay monthly to play. 
NcSoft is bad at protection their Servers from 3rd party programs.
SO they simply do what they can do which is Screw all of us over cause theres no proper Gameguard to stop program/script users
