Well, the same is true for any positive dominion. If 50% of your nation is out of your dominion, 50% isn't benefiting from your order scales and 50% of the random events will not benefit from your luck scales. The three event cap doesn't really impact this.

One non-obvious benefit of a luck scale is when your dominion pushes into somebody else's territory unlike other scales they don't merely not get the advantage of your good scales, they actually have a functionally negative luck scale for that province of whatever your positive scale is. I think the logic is good luck for player A is bad luck for player B.
