This suggests that Alliance players have more mules (twice as many mules?) than Horde players. Why would that be?And the Horde may well pull even on a lot of servers, population-wise. (The 3:1 and worse ratios have been discredited by Blizzard when they screen out low level mule characters. The worst is apparently somewhere around 1.5:1 ratio, which still isn't great, but isn't the end of the world.)
