In the one of very few cut scenes we have in Destiny, it would be cool to decide which gun your character holds for a Crucible match. Dragonsbreath, for example has the smoke animation seeing a character hold it, "intimidating" the other team would look pretty cool. Eh I just think it would be something "new" see before us guardians right to the death. Me personally would hold Dead Orbit's 1st Hide and Seek-42. What would you hold?
