1. Avatar clones which are restricted to standard TBB, which won't be damaging Sasuke's PS when it's on par with a durability which survived a Juubi laser that is >>>standard Bijuu Dama from Kyuubi. 1 TBB will only ever come close to hitting PS, Minato's TBB counter acts one with an even larger TBB while his clone uses S/T barrier to take out the third. PS shockwave exchange with TBB, or Minato's TBB overpowers the restricted to standard Bijuu Dama.
2. Sage Mode won't change, it's a balance after all. So if he could use x amount of chakra in his cloak, then x amount of chakra is being used in combination with Senjutsu this time around too. And Naruto's chakra has a negligible effect on the Kyuubi avatar. The avatar is strong because of the Kyuubi's chakra's potency, Naruto's chakra potency is pretty much irrelevant.
3. The charged BD gets warped away by BM Minato's clone. If it warped Juubi's TBB then the mini TBB's Naruto creates in comparison get warped with little trouble. This can be teleported to a marking near Naruto, which will lead to his demise as he cannot tank his own Flash TBB.
4. Sasuke's attacks are on par with Naruto's. Naruto gaining 100% Kurama does not change anything other then his chakra reserves. Kurama's chakra potency does not progress over time, it's a constant and will always be.
1. Wrong. Combination of 2 attacks equal to a standard BD already blew off half of Sasuke's wing, face, and arm during VoTE, in canon. That's from downscaling RSM and Rinnegan to BM and EMS. Give Naruto Senjutsu and give him the growth in chakra strength from the 15 year skip, and Sasuke's PS takes far more damage than what it took in canon. So Minato can block one clones BD with his own, then the charged one gets sucked up, but the third clone BD hits and does moderate damage to PS at the very best. PS shockwave from Sasuke is nowhere near the level of a standard BD so don't bother trying to use it as a counter.
2. Not even sure what you are talking about here. RSM scales down to BM, and Sasuke's PS only matches BSM. Thus he takes more damage than what he took from a standard BD in canon. Same goes for all his Avatars stats in comparison to Naruto. And the Avatar is made of Naruto and Kurama's chakra. If Naruto's chakra grows in strength, then he will be stronger after combining that with Kurama. Naruto's chakra being irrelevant is false, and Kurama being the main thing that powers his chakra up is irrelevant.
3. You do realize that if it explodes Minato and Sasuke get caught in the blast too right? :lol Naruto not being able to take his own Flash BD without dying when he can take the Juubi's laser when his tails are wrapped around his body w/o Senjutsu no less makes zero sense unless you want to start arguing that Flash BD>Juubi's Laser.
4. No, they aren't. Not even close. Full Kurama increases the SIZE of the Avatar. Thus it's physical power and durability increase as well. Naruto has Senjutsu and 15 years of growth. BM is Naruto+Kurama. If one gets stronger, then the other will obviously get stronger too. Even if you were correct and Naruto gets no boost from his own chakra getting stronger (which makes no sense since Kurama gets a boost from Senjutsu and Hagoromo's chakra) he still has Senjutsu which easily puts him above Sasuke.
Even if this were BM Naruto. Sasuke's PS slashes were being countered by the swipes of Naruto's tails and that's his strongest attack with just EMS. Even if he had the feats of using Chidori w/ PS, he'd only match a standard BD, not anything higher.
Then there are the feats that Full Kurama showed at VoTE.
