I don't think Kishimoto being too uncreative to teach Naruto anything other than Rasengan, big Rasengan, bigger Rasengan, two Rasengans and projectile Rasengan makes it a versatile technique. All it does is spin things around to destroy them.

A kunai or a sword would do the work better

It can be fused with any element.

Fusing it with wind causes molecular damage for example, burrito's rasengan turns invisible as another example. So on

Actually I can, you super reatard
