make it level 25/26 to start. high enough so that everyone doesn't do it easily and low enough to make it possible for non-level-30's. also, weapons on sparrows, customization, class specific, whatever. be cool to be able to ride your sparrow through raid instead of having to "find" a pike - also make raid fireteam makeup more diverse (1 with 50 cal, 1 with missles, etc.). maybe sparrow races with weapons - like death race instead of death match?
