Why do people use normal richness in MP?

A rich world also doubles the resource production of every province, which has a few far reaching effects on game balance.

Richness setting also effects ashen/void Ermor's starting gem production. With normal you get 10, with rich you get 15.

Yes, but this is a purely local effect, compared with the global consequences that rich or poor richness has: Ermor only has to pay once for every priest, after which every reanimated is free. Everyone else pays twice or half as much for EVERY unit.
