i posted this in the World 10 announcement, but it belongs here.
A comment on tri-quality: There's no real way to target any one quality. For example, raising a high substance drop in high vitality soil cared for with high essence... somethings.
There was the old Personal Beliefs system: Instead of a linear progress of quality it could be on a positive/negative scale (since squaring it before averaging would negate the negative).
Take Nature/Industry for example. A person with high nature might get massive +30 Substance and high Industry -30 Substance (this would still be 30 average quality overall). So people who are naturalists would get benefits in quality for continuing to be naturalists and industrialists would get more benefits from being industrialists. ... So then what? What if you mix materials with another player? Well, find someone who loves pottery to make a powerful -30 Pot for your powerful +30 tree and then... BAM! Bonuses! Form communities to mix and match specialties to get quality bonuses for everyone.
