Even if he didn't delay it, it wouldn't have change anything considering there is a time delay for the kamui teleportation when Hiraishin is instant. He would always get out
Of course it changes things, it gave minato time to react. What if obito warped minato like he did torune? Obito teleported right behind him rather than from a distance, he didn't say anything, & he didn't care which way torune was facing.

, tobirama will be forced to destroy it, obito warps behind him among the explosion.
Point? I never said that this obito can, I said that he would need a summon in order to contend if tobirama had info. It's not like obito doesn't have summons so that's why I mentioned it. U_U
Unlike 10minutes invincibility to lose an eye, the clone invincibilty is permanent with no physical loss. Clones are better for me. Besides in this scenario, Obito only has one sharingan, so losing his eye and he loses Kamui
Unlike clones, invincibility doesn't require handsigns, it doesn't "poof" when you're killed, you don't have to divide your chakra, & your presence will be erased, that means no sensing you once you're killed. Not only that but trading killing blows means nothing.
& Obito has two sharingan eyes, he didn't fight konan yet.
