[Mr Hiru]

Obito just got done with Madara and the same scenario moments earlier.

Double Kamui is twice as fast and range is probably double as well. Instead of Obito using that to his advantage he gets in a footrace?

Look at how fast Kakashi is with it. Kaguya can't even get the shot out of the dimensional opening before it is Kamui'd.

Like I said, Obito either trolled himself or Rin is an evil mastermind.

I see what are you trying to say with that, but, try to look things in perspective... Obito was almost out of chakra. Sakura had to give her Byakugou chakra to bring Sasuke into game.

You have a good point, but the variables gives some merits to the context of Obito's death.
