It also allows for Itachi to rig another time or visual based Amaterasu in the crow's eye, to catch Pein off guard.If you restricted KA, does that mean Itachi has Shisui's eye in this scenario and can still use 3-tome genjutsu[You must be registered for see links]?
itachi and kisame win.
A medium range starting distance is anywhere between 5-10 meters according to the databook, which is a horrible start for 6pop and konan given itachi's extremely fast execution and shunshin blitz. itachi has knowledge on nearly all of the rinnegans techniques (assuming it's manga knowledge) and has everything necessary at his disposal (with kisame) to counter their techniques.
Ehhh. Sure, it could probably give Pein a slight edge on the tactical side of things. Both shinobi have fallen for tricks, like Kisame losing Samehada in an explosion before, and Itachi to Sasuke's wire trap. So it isn't an abstract idea. But that's largely where her use ends, she's just a supporter in this battle.Konan can mix clones or Paper weapons with explosive tags. Those can provide many factors to trap and set up for Pein, imo.
