The high combat ability and survival ability of the Exos and the major contrast of the solidness of the starship's shell and the vulnerability of the starship's interior were the reasons the melee battle of the crystal suits was so important.
Both the shield starships that were responsible for defense and the arsenal starships that were responsible for attack, after accommodating the enormous spiritual shield and disruptive force field generators and the warehouses of crystals to power those behemoths, would have barely any room to keep more Exos.
Besides, even if tremendous Exos were deployed inside the starships, the overwhelming spiritual energy that was unleashed after they were engaged with the enemy would cause serious damage to the starship, too.
