I've stated before that Sephiroth in SOLDIER garb would be nonsensical. As an experiment, he was never a regular infantry soldier nor even an elite. He and Genesis were top-tier from the get-go. If anything, they might've put Sephiroth in a labcoat to allude to the fact that Hojo's his father (or even that Lucrecia's his mum). Or maybe just mutilate his body so he looks more like Jenova.
I hate Cloud's Amano alt.
I was at first taken aback at the sight of Squall, but quickly accepted it and Laguna's be rockin' dat Galbadian armor, baby. I also actually really like the new Onion Knight outfit; some may have a problem with his hair but at least it ain't a lame palette swap of the original armor... I hated that.
