Well, it is possible that OP is saying that the game is boring to keep seeing rook in 1v1 and slaughter them every time.
Quite possible; I've seen a lot of newbie hammer rooks out there. They're not bad when backing up an ally, but they're dead meat if they get caught alone.
Tower spamming is definitely weak in this type of game
As I said, Rook sucks at holding on to flags in 1v1. If you can't push significantly hard or the enemy isn't foolish enough to run head-first into a tower farm, you basically have no way to win.
