The best 'The Rook' strategy I have come up against yet
If you are terrible at playing The Rook... then don't pick him! If you run around the map setting up zero towers and not using any of your abilities... then don't pick The Rook! If you run in to the enemy demigod with only half health because you have no idea what structural transfer does... then pick a different demigod than The Rook!
It's a pretty simple and solid strat new players and pros alike can really get behind.
