Review Detail of oceansage in Naruto: The Outsider {Dropped}

I'm writing this after reading till chp. 13, as I really can't read more. First, this story is interesting enough and writing quality is decent(way above most fanfics). But failure to use his own whishes to it's full potential is really off-putting. Mc has adaptable body but he doesn't train physically, he has no self healing techniques, no fuinjutsu training and is only specialised in lighting, even though he has skill tree to get knowledge. i mean, given mc wishes he should be op by now but nooooo, dark chakra is cool, let's spend 8 years on chakra control so he can finally start his ninjutsu training. let's not forget about his hideout which can be discovered by kids, but somehow a village full of ninjas containing clans specialising in tracking, sensing, and seeing(hiyugas) hasn't descovered it yet.
