You, my friend, have accurately described my thoughts.
I mean, COME ON.
Kakashi stated that he wouldn't have had to make the chidori if he could have mixed his lightning chakra with the rasengan. So what does that mean? It means that Kakashi mastered the rasengan BEFORE he made the chidori, most likely at a younger age than even Naruto! Then, he created his own ELEMENTAL technique. Sure, it was incomplete, but give him props. Kakashi was amazing.
Oh, and everyone already knows that Kakashi graduated from the academy at 5 and became a chunin at 6. Look at that, a little toddler running off to do what teenagers work hard to accomplish!
And what now? He's kind of lagging... The fudge man...
