I think that you should add drillers in donor mines. This is becaue once you are in a mine then most likely you will get a driller, not before, then fortune is just better in z mine. But if you add it to donor mines it has a use, all donor mines do not have a fortune effect on it. A staff member told me it was disabled because it was "too op" I tested it and you get about 11 stacks of ores or blocks in a minute with an iron driller, 19 with a diamond, and 15 with a regular yes pick, and when I tested the zues pick I was mining in zues mine so it was not fortuned, to me, that is not "too op". This is why I think you should consider adding drillers or enable them in donor mines. Thanks for reading!
