I don’t think that really explains it (or i don’t understand what you mean). In H2016/Legacy, he has his own unique arms together with the starting outfits (e. g. Italian outfit or black turtleneck), while in H2, he doesn’t even have his own hands with the Signature suit. In H2, he has different unique set of arms with location specific outfits tho, but they are different from the Signature one and other pickable suits.
Like, his unique model of arms already exists and is used here and there, so why not just copy-paste it across all other starting outfits, instead of him having bunch of different ones, that don’t match his face skintone. He’s a goddamn protagonist, he should have his own arms.
