Alneyan, my point is still different from what you are saying, I think. If a plop is in friendly dominion +4, it might settle there to increase dominion to +5, as opposed to moving on, possibly to attack enemy dominion. If a plop is in friendly dominion +10, it will definitely move on, since it can do no more good there. Thus, having high friendly dominion and attacking enemy dominion are related. When friendly dominion is maxed out, then enemy dominion is more likely to be attacked.
Then again, I could be wrong.
