The lore behind smart weapons such as SGA say that they would develop their own personalities. Whats the point of making the exotic bounty for SGA seem like its talking to you if it doesn't put out a snappy comment every time I blow of a Dreg's head with it? Bungie, please make SGA talk in-game. That would make it one of the coolest exotics in the game.

Maybe have it place text in the bottom of the screen so it would be talking but wouldn't actually have to pay a voice actor, it could randomly tell stories of the fall or about people or give backstory if you are standing around or paying attention.
