[14] Master
Soul Edge actually uses the host's favorite style, reason why Inferno in Soul Blade had Cervantes' style before becoming Nightmare. Then, after SCII, Nightmare kept this style as he didn't have any new host (but that could be considered a plot hole, as he could use any style). But again, the idea of a mimic in the Soul series is really awful: why would Edge Master (for example), master of ALL styles, only use 20 of them and absolutely no original one? That's why I'm (normally) against mimics.I don't think it would be easier, but we can agree to disagree there, because neither you or I have the knowledge to carry that conversation forward in a meaningful way
Though, I'm curious as to why you think the entity responsible for Nightmare's existence would be doing Sophitia's or Kilik's moves at random. I'm all for a singular mimic being in the game, but I don't think it makes sense for it to be Inferno.
Except that switch required new moves.Except that they didn't put resources into making a clone playable. They put resources into making a boss use Nightmare style, which makes sense because Inferno/Soul Edge created Nightmare. That's the main point, then they just flicked the switch to make him playable.
Making him a mimic in the first place wouldn't make sense lorewise for a final boss. Not to mention there's no Soul Edge variations for any other character and it wouldn't make sense for Inferno to wield normal weapons. From a gameplay/balance standpoint we also don't know how much effort it would be because of all the character's gimmicks, soul charges and RE outcomes. It's just not that simple anymore.
Lorewise, it makes more sense for Inferno and Nightmare (no host) to have any style they want, not only Siegfried's style. There might not be variations for the characters, but that doesn't mean Inferno can't shape Soul Edge to suit him. After all, Elysium could use variations that no other character could use.
