They didn't give a fuck for Decidueye however, so regardless how the west felt, it was always going to be ignored in favour of what Japan said. And as they didn't exactly give a country-by-country split for the results, we can only assume they went as historically noted in Japan, as the factors for its hard-loss in Gen 7 still yet persisted.
