Since Naruto is pretty much the new generation of Hashirama as Sasuke is to Madara(we will know after his conversation), Naruto needs something unique to himself besides rasin-shuriken. Basically Naruto's clones are on the same scale as Hashirama's mokuton. Not in terms of power just utilization then again Naruto has made clones of a great mass. So shouldn't Naruto have clones that do different things. Like an exploding clone, a water clone or a clone that casts genjutsu on impact(would be perfect for naruto since he always gets caught in them).
