You think so? I'm not really an Armor of Light users when I do play as a Defender. Just to specify that my idea was that when activated it would just be giving yourself and any teammate around you an overshield that can be taken down and never recharge. Like a "Hey I'm about to die and if I can activate this before I am killed I can save myself and kill whoever is attacking me. Or possibly used as a way to attack an objective or a group of enemies easier.
