I know how to solve (chinese) farmer hackers and mastery book issues

So what if there's mesos remaining? The point isn't to get rid of every single meso in the game, it's to lower the supply. Instead of the money going to another person and only a very, very, very small percentage deleted from the game, all of the money will be deleted from the game. Over time, that would drastically reduce the supply of mesos in the game.

No one said there has to be absolutely zero mesos in the game for a meso sink idea to work. |:

That's one example that I'm familiar with. I highly doubt Shadow Shifter 20 is the only expensive book. This could have a bigger effect of basically deciding what class you play based on how many mesos you have.
