Yes it will, it will change everything, as whenever obito even tries of attacking he gets blown awy by ST
the continous ST allows nagato to prevent himself from obito throughout the battle,
He has full knowledge here, no reason to go straight for the kill.
Yeah thats not happening, when obito has no way of perceiving ST at all, not even a sensor such as SM naruto could,
Nagatos reserves are also superior to Obitos, and the toll on Obito getting blown away is clearly higher than nagato just using his ST,
Even if it does hit Obito, ST is just a repulsive force, on its own it has no DC at all (at least the weaker versions), it only does significant damage to the opponent when they collide with something (e.g. the ground), once Obito starts to get repelled, he activates Kamui, and thus stopping him from colliding with any objects and receiving any kind of significant damage. Or he simply activates Izanagi.
It doesn't matter if Nagato's reserves are higher. Nagato's techniques cost him considerably more chakra than Kamui costs from Obito, that is enough for him to outlast Nagato.
he is not outlasting nagato especially when he gets blown away by ST the moment he solidifies to attack, and is taking more damage than nagato throughout the fight,
Read above.
he is also not outlasting nagato especially when he has iintel on kamui and would know to only use ST when obito would manifest physically,
Obito doesn't manifest physically, in fact, he is always physically "manifested", he only warps his body parts (the ones that are about to get hit by the incoming attack) to Kamui dimension and warps them back immediately after the attack phases through, making it seem as if he phased through them, he doesn't need to be "tangible" to attack, as he doesn't warp all of his body parts when the enemy attacks, he only needs to be "tangible" to warp his opponents or himself.
Nagato having intel changes nothing, he can use ST all he wants, he isn't doing shit to Obito.
his mere mokutons are also not doing shit, they are either destroyed by shurado missiles or simply laughed at by ST
Outlasting = when Nagato runs out of chakra. He can't use ST or Shurado missiles if he has no chakra.
