Why do all tactics involving the Rook start from the Rook?

Why do all "Rook" tactics rely on this?

Because the standard online setting is 160% (Queen). It won't become any easier to win because you're not playing against a dull and outdated set of scripts, but against a person with a brain who isn't just some random guy, but someone who also makes moves on their own.
Why not 200%? To level the playing field. Since 99.9% of the time, players get random maps, there's a "dispersion" where one player gets chests and gold and can buy heroes and develop (scout in different directions and gather resources), while the other might simply not get anything and will be running around for 5 days with just one hero. That's why everyone starts at 160% "for balance."
