I fly for the smallest side. It results in more fights and more points, which is all I really care about. If you think forcing players (like myself) to stay on your side for an additional 11 hours is going to somehow help your cause, then, well, no, it won't. If my side has too many players or an overwhelming advantage (like it typically does past midnight CST), then I'm going to log off. The second that 12 hour limit is up, I'm going to log back on and switch to the smallest side and proceed to kill whoever that side is fighting.
But seriously, they're stupid chess pieces. Unless you swore your lifelong allegiance to some guy in armor riding a horse, I really don't see what the problem is.
