Well Obito really died thats too bad but whsts worse is his mangyeko is also gone . The least he should have done is gorge out his eyes and give them to Kakashi, anyone who thought the same?
Eye don't think anybody would want to do that in their final moments, it would have ruined everything (see what I did there?).
That would have been cool if it happened like when shisui have itachi his eye and than died.
Finally, no more Kamui hax. However, Kishi should've left Kakashi with only a 3T Sharingan, would love to see his 1000 jutsus, atleast some of them before he dies or the series is over.
I thought Obito would have said, "Kakashi... thank you for still believing in me and being my friend... I almost forgot *gives him his Sharingan* this belongs to you." And then died like the chapter shows.
