The map was designed so both teams can win no matter what happens. They just have to play the game right.
This isn't about favoritism towards sheep or shepherd. This is about what is fair. Just because 90 - 99% of the community favors sheep over shepherd doesn't mean it's right to allow more time for team 2 to mass more than what is required in the 2nd round.
You're all arguing that it is a rational decision, if team 1 sets the time limit for team 2, to AFK until the first team is done playing. This is ridiculous.
