They did 2 or 3 tomoe Sharingan no longer has any purpose because now 1 tomoe has all their abilities.They didn't screw anything . Stop lying there are many threads about Sarada excluding mine. 1t sharingan was never stated in the manga to not be able to perform copy and genjutsu.
That doesn't mean its filler its just mean they made a mistake giving others material to bash anime and call it filler.
