'kill all enemies'
'no heavies'
'no deaths'

Something to reward performance in addition to completion. Right now Strikes have devolved to speedruns; if you don't have to shoot it, don't.

Like the nightfall and heroic weekly strikes and the raid reset, we could have a weekly set of bountys reset! they would occupy a different slot on the inventory screen so they dont clutter the dailys but would be a lot harder.

Examples

• No, no, no - Kill the Templar in the Vault of Glass without letting him teleport.
  The big Cheese - Kill Atheon in the vault of glass with the heroic modifier.
  
• Angry Saint - Kill the Templar in the Vault of Glass during his enrage period.
  
• Left, Venus, Mars, green! - Kill Atheon in the Vault of glass during hid enrage period.
  
• Now I'm Kabr, right? - Kill a gorgon in the gorgons maze.
  
• Immovable object - Complete the Vault of Glass without letting a vex sacrifice itself to a conflux.
  
• Completionist - Complete three missions on [Earth/Moon/Venus/Mars/etc.] at level 24 or higher.
  
• Incinerate/ Obliterate/ Paralyze - Kill 200 [fallen/hive/cabal/vex] with [void/arc/solar/] damage.
  
• Bombardier - Kill 100 enemys with explosions
  
• Grocery list - Complete 3 daily missions and 6 daily bountys
  
• We need more like this - get 50 kills with the Sword of Crota, at level 24 or higher.
  
• One shot wonder - Kill 100 enemys in one shot (no melee, that's too easy)
  
• The true light - Generate 50 orbs of light
  
• Dance, dance, baby! - Dance with 25 different guardians
  
• Only way... farm 50 [spirit bloom/helium/spinmetal/relic iron]
  
  
  These bountys would be made for the higher level player and someone focused more on endgame
