Okay woah, some of you guys are overlooking some things, now i may be wrong but:
1.white zetsu is the only one capable of creating a "perfect" clone of someone, and as we saw in the chapter, he has to be with the body. so, naturally, should we not assume he can only make one clone at a time, which explains why he isnt a one man army, or why other clones have been made in the past by less effective means?
or am i just not remembering something?
2.sakura isnt useless, you guys are making a self fulfilling prophecy here, just because she will stay out of fighting sasuke (which she should) doesnt mean she is not going to be useful
maybe she can learn from karin's example, that being infatuated will only serve to screw you over, neither of them were actually in love with sasuke, they just had crushes...really, i cant think of a better term to describe it better than infatuation - "a foolish or all-absorbing passion"
then, once she gets away from this crap with sasuke, she can finally grow the f**k up, and be the damn medic she is supposed to be, and then characters outside of naruto can actually fight big scary badguys, because sakura would have the capability to heal them, instead of sit around and whine about it.
i mean, look at her prior to the attempt on sasuke's life! she was cold, calculating, then she sees him and bam, its back to being crap, if she TRUELY has changed her mind about sasuke, then maybe we can see her put that resolve into action against other foes
