Why can't Kakashi use Lightning Cutter properly after losing his Sharingan?


Is Kakashi's new technique _Lightning Release: Purple Electricity_ as powerful
as his signature technique, the _Lightning Cutter_?

On [Naruto Wiki](http://naruto.wikia.com/wiki/Kakashi_Hatake), it is written
that after losing his Sharingan, Kakashi can't use Lightning Cutter
**properly**. What does this mean?




Kakashi can't use the Lightning Cutter because it creates tunnel vision
without the Sharingan, leaving him open for counter-attacks.
