yeah i only put in ms there, because naruto and sasuke have always been balanced out, and as zetsu considers sm naruto to be stronger than ms sasuke, a naruto with a stronger sm would be leagues ahead of base sasuke.
about ma and pa, agreed, it's a bit of a weakness. it's partially compensatable by naruto's increased threat detection in sage mode though, unless you use bansho tenin like pain did it's going to be very hard to hit naruto, or the frogs.
naruto's clones is an excellent method too, but of course once he gets out of sm his power will decrease and he will find it hard to summon them using the scroll. personally, him making 5 clones, having 3 gather chakra somewhere far away and two helping out seems better. merging with ma and pa seems less of a hassle to me, seeing as he can enter into sm much quicker now, and could spam as many clones as he wants without a care for disrupting those gathering chakra. he could always revert to the clone gathering method if ma and pa are incapacitated

by that time the battle will probably have ended though hehe
