I think that destiny should have some cool wildlife aliens and beast. This would nake a cool addition to those parts of the planets that have nothing in it. For example there are big empty paths in venus and that could be filled with cool wildlife enemies. Big wildlife beast could also be used for public events in which you and your team have to work together to bring it down. This would also bring new challenges like hunting ones. There could also be rare animals that could drop materials or some kind of good item. I think adding big and small creatures would bring more life to the game. Im not saying that you should make a bunch of animals but a few would be nice.
