I have been trying to collect as many of the sparrows and ships as I can and unfortunately Amanda Holliday is not very helpful when it comes to her rare ships. A 72hr refresh on her inventory is to long, especially when it is just a chance that a ship you need will be available. Bungie Please Decrease her refresh timer to 24hr, in addition to this it would be fantastic if you could controlled her inventory so she always has 3 common, 2 uncommon(Green), and one Rare ship(Blue) available.
