Up until now, the Larkinson Clan's approach to glows was just to make use of them whenever convenient. There was hardly any greater thought behind their use because they were just there already.
The Avatars of Myth, which was arguably the greatest user of glows in the Larkinson Clan, just took whatever mech that Ves shoved at them. It was up to them to figure out how to make effective use of the new glows.
This was a rather faulty approach. What actually needed to happen was for Commander Melkor to approach Ves and request the addition of a mech that fulfilled a certain role or requirements. The needs of the Avatars had to fit its chosen doctrines and approaches.
