I dont know but that example is quite ambigious . There should a be a bow and an arrow super and bam it happens? Thats a wish , a suggestion . A wish that leaves room for work. Work that the devs can sell as their own. This right here is detailed abilities , everything worked out . No room to work. They would never adobt this. It puts certain people out of their job. Aint gon happen. Its different if i say : "I wish there was a fourth subclass ." Thats a general idea they could pick up and run with.

I'll never go back and find these posts but I can remember two exact posts that laid out the entire subclass perk tree nodes and they both suggested a bow for a super. One of them even had the grenades as a smoke not the melee however. Of course you'll just have to take my word for it but this is evidence enough that these posts did exist and that bungie could have perhaps drawn ideas from them. But I have no proof for anything so yeah, there's that.
