why doesn kakashi use the rasengan?

[EliteKakashi]

about Raikiri or chidori

1. it can be mid range like he does fighting pain and like suske use
2. even if it is short range you can't say it makes kakashi a short range fighter

Kakashi is a CQC fighter though. The only fight he's ever been in that was a "ranged" fight is vs Deidara, and that really doesn't count.

Rasengan is not his own so he don't want to use it.I wonder kakashi can copy rasen shuriken also???????????????????
