Wait til the first, humble, it will be somebody else in the barrel. I've watched it for over a year now. When I first started, it seemed like the Rooks had a large Asian contingent because invariably, at 9am or so, the rooks would control a large part of the map! At U.S. prime time, it seemed the rooks were always outnumbered.
The Knits *ALWAYS* had the largest body count during U.S. prime time and the Bish hung in there, always with fewer numbers.
It's different now and I don't know why, but the Knits are frequently outnumbered. Is it because squads rotate at months end? I don't think it's that simple.
Anyway, I noticed the Assassin rotated to Knit recently, probably because of concern over numbers.
There have always been hills and valleys with player numbers -- in the past, maybe it occurred when you weren't ordinarily logged in?
