I have a package and about 5 or 6 Engrams just waiting there.
Also, to tack onto your note about killing the Hive Majors/Ultras, if you have the bounty for killing Fallen Majors/Ultras, there's another Queen's bounty that has you take out some dude on Venus, Draksis or something. The dude who has a fucking throne room. Anyway, before you hit the cave to start heading towards his ship, there's a bunch of Fallens there, along with a Fallen Captain who is a major. You can stack the Draksis run, killing 200 Fallen with headshots, getting 200 precision kills, killing 10 Fallen Majors and picking up those one drops for the Queen all on that entire story mission. However, that first part with the Fallen Captain you can farm in about 15 to 20 minutes. You may spend 45 minutes to an hour total on that story mission, but you can crank out 5 bounties all at once.
