Garp, going back and forth from headquarters to east blue with the excuse of vacation, just to visit his son to his grandson weakened east blue. The very reason why the old man loves cannonball pitching very much is that he might have done that kind of thing as sports in east blue. And you know who the targets were. So the very reason it was called the weakest is because it's much more peaceful and the overall quality of pirates are becoming more and more inferior due to Garp's frequent "vacation".
