The reason why we don't bash kakashi is because, Sasuke has a choice of turning the Sharingan on, And he has it in both eyes. While Kakashi has his Sharingan activated at ALL times. Now if you were in a battle, Would you rather fight with one eye closed, or no eyes closed. Answer is simple, You fight with neither eye closed. Kakashi has to use his sharingan for fights because he needs to fight with both eyes open, Otherwise you've got a blind spot. Sasuke does use Sharingan for everything. Of course he's not going to activate it when his opponent is standing around.. Seriously without his Sharingan he's dead. Killer Bee would have easily won if not for Amaterasu. I'll agree Naruto was weak during fight with Haku, But who ultimately broke Haku's Ice Jutsu? Naruto with 9 tails chakra, Not sasuke. Again with gaara, Who beat Shukaku Gaara? Naruto + Gamabunta, Sasuke even thought Naruto was going to surpass him. There's no reason to bash Kakashi. He doesn't depend on Sharingan, He needs to use it otherwise he leaves a blind spot. Sasuke depends on it, Without it, Well, Deidara would have blown him up with C2 Dragon + Mines, and Killer bee would have killed him with 8 Tails form. First project for you, Remember the basics

. Itachi never wanted to fight anyway, If you go back to Madara's talk about Itachi, He says Itachi was always a pacifist, He hated fights and tried not to get into them, If he got into them he'd always find the easiest way out. He could see without it, He never went completely blind, His eyes were white by the end of his fight with Sasuke but he could see Sasuke well enough to transfer Amaterasu and maybe the other techniques.
