My only complaint so far is how suddenly dynamic weather changes as you one-step ahead to the next place. From Rolling Fields to South Lake Miloch, it suddenly snows. Go back to Rolling Blades, it rains. Turn left, it starts snowing in Lake Axewell. The change is incredibly fast.
I've been to Scotland many times, and the weather up there really can change suddenly! I've known there be sun, rain, hail and snow all in the same afternoon before. While I doubt Game Freak had this in mind when designing the Wild Area, I find it amusing that they've inadvertently produced a really accurate depiction of Scottish weather.
