What I don't agree with is that Mangekyou user only has 2 powers, with each eye controlling a different aspect of 1 power and the 2nd being Susanoo, because Itachi got Amaterasu, Tsukuyomi and Susanoo. It fits in most cases, though. Sasuke got Amaterasu in one and control of said flames in other, Obito got different aspects of Kamui in each and so on.
