I think it would be more fun if kills with the bow summoned a red hued 'taken' version of that enemy upon their death, that fights for you for 15 seconds. Obviously doesn't work on enemies that have no current taken variant. The perk would allow up to three taken allies. Kills greater than that amp up your allies damage and duration. This can last indefinely IF you have the enemies to farm (but there is an add damage bonus cap at 300% bonus damage). [spoiler]You get it, taken? Taken by love?[/spoiler] Besides, we have nothing in the Destiny universe that summons add like allies to our aid so far (besides Arc Souls). This would be a great addition and dynamic to PvE. One more thing, I want the empahsis on summoning new allies (rather than taking current enemies) because the latter 'can' make games last longer because the game sees 'not all the enemies are dead' simply due to their turned state. By having actual summons, this won't be a problem, as the game won't confuse allied adds to enemy adds.
