I looked over each virago dragon, and they all possess the war and light elements. Social Point, I do not know if this is already planned, but you could add a Virago Habitat as a special habitat which uses either element (war or light, your choice) and could be a lap prize in the heroic race.
I think this gives players another thing to work for, and something that they can put all their Virago dragons in. And in addition to that, it could start up another collection of limited edition habitats. (Like the Zombie Habitat)
This was just a thought, and I hope you take it under consideration, even though their is only three days until the heroic race.
