Here it is in layman's terms.
When 1 country gets within 4 hours of winning the map, a whole bunch of dickheads feel entitled to the measly 25 points for the war win.
So they stay logged in, drive eny up above 25 and the rest of the country is stuck with junk planes to take enemy bases with, even though there is no real numbers advantage because the overwhelming majority of people logged in are not playing.
