Minato is only godly fast because of FTG. I feel like any Uchiha can rival his natural reflex with the sharingan. He has good reflexes but speed=/= reflexes. Minato is nothing without FTG deal with it.
So to which would you constitute reflexes with? Last time I checked, great reflexes are possible with great body speed. So fast reflexes may only be achieved if one has great speed, or a rather more agreeable term, great
agility. If you still do not agree with this statement, I would like for you to watch a documentary about the special ops and counter-terrorists and even just those who practice the art of Krav maga and
REAL ninjutsu and how they manage to fend off a great number of enemies and how they manage to disarm about 2-3 armed persons in 5 seconds.
Of course Minato is indeed godly with FTG. That is his signature jutsu. He created it.
Saying those bolded letters in your response is like saying that Madara is nothing without Mangekyou Sharingan, Nagato is nothing without the Rinnegan, Kakashi and Obito is nothing without Kamui, and Naruto is nothing without Kurama.
To be fair, all of the signature feats of my examples are natural to them, and in Naruto's case, he lived with it, pertaining to Kurama. Madara and Obito has the sharingan, giving them a lot of potential, but if we think about it, it is in their blood, so there is naturally no basis of comparison if we compare them to others who do not have bloodline limits, and by your logic, we can say that their feats are in their blood, and they are nothing without it, so we should deal with it. In Kakashi's case, his sharingan was given to him, so by your logic, most of his feats came from a gift, and he is nothing without it, so we should deal with it. In Naruto's case, he got Kurama sealed inside him since he was an effing baby, and he is only godly because his father sealed it inside him, and by your logic again he is nothing without it, so we should deal with it.
In Minato's case, he has no bloodline limits. He created his jutsu from scratch. Unlike my other examples who has potential in their blood or is a jinchuuriki, Minato has nothing to start from, rather than creating and training jutsus which would make him godly, thus Flying Thunder God.
