I'm genuinely unsure if cultivating anywhere other than in willowbrook or in the harmonized settlement gives any affinity, I don't notice it go up in for instance, the wilderness, the dual element towns, or even in the imperial city.
It's either that they're broken in this regard, or that they just give so little affinity that it is effectively nothing.
Honestly I never checked the wildnerness after realizing that harmonized provides a unified bonus. I'll just test the wilderness wandering and see if affinity increases.
Mono Outer: Doesn't not do it, or its very slow. Didn't see any gain in 500 years
Mono Inner: Wandering does not increase affinity. same as above
Dual Outer: Wandering does increase it but at horrible rates, harmonized settlement is superior.
Dual Inner : Marginally better than Outer
Mono Deep: Same Pace as Inner/Outer.
I agree with your wilderness findings, they are most definitely broken because I remember getting far better returns from wilderness for affinity gains. I also am not sure if this is because I'm band 17
