The problem is that if Ravel gets taken down during the game, Ise won't be able to respond to the enemy's tactics anymore since the strategy department is entirely up to her. As such, the team will be weakened and it will be easier to defeat them. Indra was probabling warning Ise that he has to improve himself further and be able to strategize on his own if he doesn't want opponents like him to exploit that weakness.
