I got another suggestion.
Atm breaking a melon yields 3-7 slices so $0.36 to $0.84 I got fortune 3 and about 600 herbalism and get up to 15 slices per melon block, so it seems that double drops work as breaking it twice.
Breaking crops yields me 1 wheat and 0-3 seeds $0 to $0.36 And $0.30 from the wheat. 0.30 to 0.66 total isn't alot.
It also seems that double drops on crops only applies to the wheat and the fortune applies to the seeds
As a crop farmer you gotte replant your fields aswell and that doesn't earn you alot of money especially considering it costs seeds.
So i would like to suggest that crop farming is buffed, Perhaps the nicest way to do it is to increase the ./sell value of wheat since it doesn't scale with fortune as much.
It would also allow us to invest in haybales to evade town taxes.
To be honest 1$ per wheat seems like a fair price, Considering that you have to break the crop and plant it. perhaps $1.5 But that would make fortune hoes worth less.
