Comparatively to the other "shit" thats out there its STILL 99% better than everything else. Sure there are other gems out there but expecting Shioon to already be a super badass is a bit much. Its kinda like how Naruto had all these gifts and sucked ass until the last 2 arcs.
it's not badass, it's that he's been super emo and meek the whole 200 chapters.
"Wah, 9AD broke my ki center and i'm the gaju, Wah!"
he was an annoying nag that never grew out of his meekness this whole time.
how did Naruto suck? his only gift was also his main source of "HOLY SHIT i'm 4 tails and WTF out of control"
From the 3 year time skip, he "completed" the Rasangan jutsu that neither Jiraya or Kakashi could complete (add element to it), he used it to take out an AKatsuki member (kauzu).
He then learned and achieved perfect Sage mode, took out multiple Pains, and used his friendship jutsu to reverse shit.
Then he sub-dued his greatest power and fair the 9tails (of course later on, becoming friends) and then the war and shit.
Shioon, didn't do shit, hell if that dead bitch in stasis didn't give Shioon that super expensive once in a life-time super medicine ki ball, Shioon, would still be a meekier person, he's been relying on the wonders of the super medicine ball all this time.
He's basically the korean version of captain america and the super soldier serum, or super steroids, except cap wasn't meek, he was just weak, Shioon stayed meek, and just putz'd around training cuz everyone thought he was an oddity.
