I do some BG's during the day, but mostly play at night. My battlegroup seems to have two very different types of people playing depending on the time of day. Before 5pm, Alliance wins most matches...usually going 2 to 1 or better. After 5pm, Alliance couldn't get a win to save their life...usually winning about 1 out of every 8 matches or so. What is happening in the afternoon that isn't happening during the daytime?
