The only way he can hurt Bee is using close range fighting, Bee has high durability, Samehada and lightning release so I don't see him getting hurt by lightning clones and he could easily react to any of Kakashi's attacks. Plus kakashi kinda sucks without his SharinganKakashi.What can he do agaissnt the swword dance? Avoid close range fight and use clone feint.He's smart,we are not talking about Sasuke.
