But - Sasuke isn't even copying Naruto's movements here. He simply sees them beforehand. I see your point about "copying" jutsu, but that isn't what I'm talking about right now. Just predicting the enemy's physical moves is an important factor in a fight, but Part II lacks mentions of it.
FOR EXAMPLE: Fu and Torune fighting Tobi. At some point they actually simply ran towards him trying to trick him or something and then seemed surprised that he "saw through" them. At which point I was like, "Really, Sharingan can predict your movements, you fools". Well, maybe, just maybe, they forgot about it or had no intel, but this isn't the only example. Others might have not failed so hilariously but still, no word of movement prediction. And notice how Sharingan users never brings it up either.
If I'm wrong about this, correct me. And again, I do NOT mean the jutsu-copying, I mean predicting movements only.
