We also need to consider that more placeables that are in an area, the greater the lag is going to be. Too many items on the ground, too many corpses, too many placeables could effectively make playing in some areas unbearable. A single placeable to put fliers on could reduce the lag. This is another reason why I heavily suggest merchant happy PCs use buildable chests, or carry around ones, to put items in rather than on the ground.
And with the talk of the lag/delay with the server move, reducing lag should be important.
