Also people have a strange belief that only their country has people sitting in the tower, when common sense would tell you that all countries would have a close to same % in the tower, and hence kicking them out would not have any impact on the ENY. In fact if you believe it could lower the ENY , it could just as easily raise the ENY.

Statistically "most" of the time that is probably true, but there are instances where you get 2 to 3 standard deviations away from the normal where you happen to have an unbalanced number of players sitting in the tower from one particular side actually affecting the outcome. Just like if I flipped a coin 10 times and recorded the results day in and day out. A couple days out of the month I might come up with 8 heads and only 2 tails.
Personally I don't think people should be booted due to inactivity in the current state of the game. Leaving the players in the game unwittingly creates an illusion during log in that there are more players actually playing than really are, which I think is good for the MMOG selling point.
