If we could use our ships as fighters,it would make ships more useful and urge people to buy them. Theres no point in buying a different ship if all it does is take you from a to b. A task that the first ship you get can do just fine. This could also add more activities to the already huge game. In story mode we could get tasked with destroying an enemy crusier or space station. For missions on the moon fellow guardians can perform a strafe run to help their teammates pinned down by devil tanks or a bunch of enemies. As for multiplayer we can have dogfights. With this they can also add classes of ships to Destiny. You can have heavy armor ships that have massive firepower but are slow or light nimble ships with weak armor but speed to make up for it.
