The final boss should never give trash like a shader or a ship or three shards. A sparrow? Fine. At least it's something you can use. You should never get a class item that can't even be broken down into shards from a chest that other players are getting exotics from. At the very least these class items should break down into more shards than a normal piece of armor. Cosmetic/useless items/ascendants are not adequate boss drops.
