well nookzer if you pay enough attention you'd notice not all the rooks have the insane strength, especially to the level of the female on the main team, they are stronger than regular people yes but they don't have the insane super strength. or else the main guy probably would of been bitched slapped pretty easy in the one fight where he has to fight a rook and 2 pawns all by himself.

which if you wanted them to Her level then you couldn't have a sacred gear because it would be to powerful there.
