Defeat 10 Fallen Hive Vex Cabal Taken Major or Ultra Location Guide
Fallen
There's many options for Fallen majors (heroic The Archive, normal A Kell Rising, Patrol Cosmodrome ), but I tend to use Wolves Gambit for a few reasons, the biggest of which is that you can also farm fallen captain kills with the gunsmith sniper.
Simply leave the last scorch captain alive (he'll end the mission) and jump off the side.
additional bounties: patrol Venus, Eliksni hunting, and a pretty decent spot to group sprees of heavy, special kills
Hive
Siege of the Warmind (Heroic)
Most people should know this one. It's kind of a bummer that we can no longer save heroic checkpoints, but it's worth it to sparrow the extra 30 seconds, as you get three extra major thralls. Simply don't enter the room with the major knight to keep the checkpoint (jump off the side) although you can kill him.
additional bounties: basically all of them. This is the best bounty spot in the game
Vex
Vault of Glass (normal) Citadel Patrol
Vex majors don't really have a story mission, which sucks because Taken can despawn your targets. There's still a shortcut, though. Select normal VoG to spawn at the waking ruins, then go right to get to the citadel. Your possible majors: two minotaurs at the top, one minotaur by the conflux (accompanied by two red bars), a possible yellow bar harpy and goblin at the cave spawn opposite the two minotaurs, and a possible hobgoblin spawn on the far corner. If you get lucky there's also a vip target bounty that's up the stairs for an extra minotaur.
additional bounties: minotaur fusion kills for gunsmith, patrol Venus, kill 50 Vex , kill 50 taken, Vex primary kills for gunsmith
Cabal
Enemy of My Enemy Or Exclusion Zone (Heroic)
Tons of options for cabal, too, but this might be fastest. Spawn in, kill all the majors guarding the door, then patrol the area for the last couple you'll need. There'll be major Centurions that spawn very frequently. Alternatively, the heroic Exclusion Zone is still very effective. Nine majors spawn out of the second drop ship, just leave one enemy alive and wipe. Everyone should know this one.
additional bounties: kill 50 hive, kill 50 cabal, gunsmith test weapons for hive, cabal centurions, cabal, patrol dreadnought,
Taken
My favorite little known spot. Spawn in, walk ten feet, and three major taken psions spawn. You can either kill them and jump off the side or let them multiply.
additional bounties: kill 50 taken, heavy spree kills, super kills
