[Discussion] Think about it.

You know, when you think about it, Juubito should have been invincible. He had Kamui for f*** sake. why did he never use it. Only to be beaten by Sasuke and Naruto. If he had been using Kamui, that would never have happened. They would have had to involve kakashi in the fight to beat juubito which i doubt would have worked cuz kakashi would have had to warp "Friendship Rasengan" to the kamui dimension. juubito should have won but plot.

I believe you could only use rinnegan tech in juubi jin form. I remember Madara saying something about not being able to use Susanoo.

Madara didnt say that.

Ot: He couldn't use Kamui.

No and Maddy used Kamui as juubi jin when he was biscted by sasuke

Kamui got Nerfed. The Juubi was blocking him from using it as he didn't have the degree of control over it like Madara did. Call it Plot convenience otherwise you are correct no one would have been able to stop him at all and the manga would have ended with everone in IT except for the edos

Hmm must have read it somewhere else then. I guess it was plot.

 

[rollin]

You can't use kamui to phase through attacks when you're the juubi Jin but you can teleport your whole body to the Kamui dimension

 

[I'm stupid real stupid]

All the main villans were nerfed

He figured he couldn't use Kamui as a Juubi Jin, yet we saw Madara using it later no problem, I guess it's due to the degree of control he had over the Juubi.
But still, he could have won regardless of having the ability of using Kamui, it just that he doubted himself at the wrong moment after being affected by Naruto's TNJ. :/
