My friend got gjallerhorn recently off hard mode crota's end and he was saying if only gjallerhorn was in year 2 so I said I would ask bungie so I have. Also I'd like to see thorn so that's the part about exotic weapon bounties

It seems to me that most of the year 2 exotics are obtained through exotic bounties. They just call them quests now. They're the same idea though.
