WvWvW - Server Population- full always win
I can understand your fustration, but it is not a bug. As the servers begin to win and lose matches your server will begin to be paired against similar servers regardless of the server population.

I thought WvWvW worked like a bracket system where after each reset the winners went against winners and losing servers went against losing servers. So as time passes there will be more balances between what servers play against each other after resets.

As stated by Mira, this is not a bug. The 24-hour rounds are to get worlds matched up against other worlds who place near the same in WvW matches. Once matches balance out some, we will turn on the full two-week rounds. Winners won’t come down to which worlds have more players in WvW because worlds will be matched against more evenly matched worlds.
I hope this helps to address your concerns.
