Ultimate plan to stop the inflation

Uhh, actually that was one of the suggestions in my first post;

No, it wasn't.

My implementation would be that all monsters stop dropping mesos and it wouldn't be temporary.
A temporary halt achieves nothing and does not at all prevent farming in the future.
Similarly, botters would have no problem farming on low-level monsters if that meant the best profit.

They could still bot for ETC drops and armor drops in my scenario, but the idea isn't to completely stop inflation.
As IceCorp pointed out, that's impossible.
However, cutting off what is possibly the biggest contributor to meso generation would have a lasting impact on the speed of inflation.
