Hello friends!
We all know that the rook is a very effective instrument, it delays opponents' attacks. However, it is made of wool, a material that is not very resistant, that is, a flame bomb or scissors would be enough and quick to open the way.
So I come to propose adding stronger towers, made of wood, stone of the end or obsidian.
That way, it would be more difficult for an opponent to get through it, and teams can protect their beds or block the way more easily.
