Hey man, I like your idea but iff you want bungie or anyone to acknowledge it you need to go in depth with it, and what it would do and how it would work. For example if I came up with your idea, I would first think of how I would like it done. So I would say they could add one called Acid, and it's icon is green and there is enemies with Acid shields and in the expansion coming later this year every class got a new subclass designed around the Acid burn. So the for example the Hunter got knives with it's super like the gunslinger's melee. And the Super could have say 20 knives thrown with the super? But it required precision and was one hits to upper body and weakened the lower body, it has the smoke grenade like Nightstalker and blink and triple jump. It's melee is one throwing knife which does Acid damage. Obviously this could be describe more in depth and maybe it's op or a little weak.
