i know that could be a dumb idea for loftar who has other ways to get what he want for that game, but...
we have a purity cap linked to profiencies like Pots&Pans, Mines&Mountains, Frontier&Wilderness for herbs and Hunting&ghatering for fishes.
not why we can't have Stock&Cultivars (maybe combined with Natural Philosophy) like a cap for the GAIN you get in term of points from a generation of trees or a field? counting the high value for humus in the purity output my idea will screw a bit highing big purities again but still not too much, helping poor noobs to grow and reach the 10% cap (that seem to be now) and vets to stop in some way a bitter higher than others
what you think? if you want to say "no i don't like" at least give a reason please ^^
