Good to know, thanks.
You know
Chibi-Reaper, I think I have to take exception to your earlier commentary about Sharingan, at least in part.
Honestly, you could just make them learn jutsu and steal them on demonstration in traditional Uchiha fashion, but the problem with stealing jutsu with the sharingan is that you learn them exactly as they're being used. When you stole the transformation technique it took you much longer than you will ever admit to force it to do anything but turn you into a duplicate of an academy teacher. Seriously, that crap went on long after the joke wore thin.
In order to do anything else with the basic transformation technique you effectively had to un and re learn it and you honestly feel that you wasted much more time on it than if you'd just learned the technique from scratch and then altered it the way you eventually did.
This completely leaves aside the fact that you're left sitting on your ass and picking your nose until someone else learns the technique that you then have to un-and-re-learn after stealing.
.... Well, if you want to bother doing more with it than using it exactly as it's shown. Jutsu stealing isn't the perfect bloodline like the clan would have you insist, but if you're going to just grab a one-off jutsu to use like a thrown kunai and then ignore forever, or steal so many hundreds of techniques that you have a pretty good one for just about any situation, then it's still all right.
Just not so good for training. None of the exercising your own ninja magic with failed attempts, and it'll probably take other students your age longer than a single all-nighter to get an E-rank trick like the pencil sharpener down.
Here, this blurb used Transformation as an example of a particular failing of the Sharingan: the way it can retard proper skill cultivation in exchange for instant learning.
While I don't begrudge the example as accurate, I don't think it addresses a huge point for all Sharingan-based-Training considerations.
Namely, the Sharingan, copies/memorizes
what it sees... and the example you gave was of a technique that normally wouldn't be visible to its user.
I posit that the Sharingan are indeed handier to have than not, for training of Jutsu that are directly seen by their users. Your fireballs, lightning bolts water cannons, shimmering air shields, earth walls - primarily the elemental stuff that's the core of offensive Jutsu - all of those the Sharingan
can help - at least for Mio. Because her eyes are near enough to always on, she's going to memorize and copy each rendition of a technique she uses. She'll recall, forever,
exactly how bright this technique was, how it impacted the training ground, how fast it moved, if its flight path was straight or curved, all sorts of useful details. And this information, she'll accurately keep sorted - she'll
actually be able to tell which of her thousands of pencil sharpening attempts was the fastest, for example, and can then use it as a reference for speed. Similarly, if she wanted to learn how to hook fireballs, she could cross reference the different mistakes that made fireballs curve this way and that for her - and do this with certainty she's not mixing things up.
Further, I don't see why this couldn't be applied to techniques that are picked up via Sharingan copying, so long as they still comply with the 'produce innately visually referenceable results'. Say, she copies how Itachi does a Fireball jutsu, and then afterwards starts making records of how the jutsu does when she twists her chakra like
this, or changes her handsealing cadence like
that every time she tries it by pure dint of always-on-Sharingan. With that, I'd argue that she'd be faster at honing that fireball jutsu, then an equivalent non-Sharingan kiddo who'd spent the time to regularly learn it up to the same level of competency she skipped to. Assisted learning in the form of unforgettable, perfect records is something that's been consistently proven advantageous in real-life, and I don't see why it wouldn't apply even here.
The Sharingan, if modestly, would seem to be an advantage to anyone that wants to master a given externally expressed jutsu, no matter the origin.
...This isn't
relevant to Mio yet given that the only techniques in her library this would apply to are ones that are too boring to be worth the mental effort, but I felt it was important to bring up. Maybe it'll inspire someone to use chemistry and macguyverism alongside a recollection of what sorts of stuff was
fun as shit as a kid, and figure out a way
MIO could kitbash the firestarter technique into some sort of fire-punch jutsu. Maybe it'll make some TTGL fan with a backing in engineering show how the forces that
have to be at work in the pencil shaving jutsu could be readily and easily scaled into a practical and lethal technique with minimal change in power demand. Who knows - a kid's passion to
learn play can be a mighty force, if properly tapped.
