I didn't mean them to be so easily defeated but you guys posted an attack where they get owned very easily. I don't want to make you guys edit your posts just for that but for the future, Vygorns are pretty strong, and the important places are going to be defended pretty well. So don't just walk into the Military base for example and own everyone.
Second, you can use less energy and kill more efficiently. E.g. Aerylin could assassinate someone by literally taking the air out of the person's lungs. Instead of creating massive air balls or whatever. BUT! Air balls are way cooler so use that ;)
