whats your point, how many characters have original moves huh
list of characters whos majority of jutsu aint original
naruto(rasegan, summoning, shadow clones, bijuu bomb)
sasuke(sharingan techs, chidori, fire style and summoning)
sakura(medical ninjutsu, inhuman strengh, summoning and herr new seal)
shikamaru(shadow manipulasion)
ino(mind trasnpher)
choji(expantion jutsu)
neji(gentle fist, rotation, air palms and byakugan)
lee(his taijutsu which is the style of might guy)
jiraiya(fire style, summoning as he learned it from the toads who also summon, rasengan)
hinata(gentle fist, byakugan and air palms)
kabuto(who basically is made up of dna and uses overs techs)
and many more
its not about originality its about how you use them so minato having ftg does not get diminished just because the 2nd had it 1st and actually rasengan is his own original move as he created it and the people i listed will have original moves but majority of their moves are from clans, kekkai genkai and their sensei
