That's some crazy EXP gain, and I wonder if there's any way that I can change it, like I can with the spawn rates in the config file.
I enjoy working for those levels, and right now they feel given to me without even trying. It removes the satisfaction of the challenge, and while I can understand some people don't want to grind, I bet there's quite some people who'd like it customizable.
If it's there, can anyone tell me how I can change it, and if not, will it ever be implemented?
