Do you think that the Otsusuki should've had a chakra absorption rather than Jutsu absorption??

Allowing the Otsusuki to absorb chakra rather than absorbing Jutsus are but more difficult to write and makes the ninjas struggle more. But that also gives us the Naruto and Sasuke be more creative in their attacks rather than punching harder. There's already movie where Naruto fought someone who can absorb Chakra from Jutsus. This would not only overshadow Naruto and Sasukes unpredictability in fights, it also makes the new gen Shine.
