Honestly I don't think this is an issue. Okubo is smarter than that. The soul calibur 6 team obviously knows that Amy is a popular character as is Cassandra which is why they are currently DLC. the fact that people like viola and many many people really like Amy as well mean is that there is almost no possibility that there will be any removal or replacement of Amy especially now that she is DLC. I don't think they're going to be repeating mistakes from scv, project soul is smarter than that. As for Zwei, I feel like if they gave him a bit of a design overhaul costume wise he'd fit a bit better. also before I checked the age I did kind of think that Zwei was in his late forties, and since his age was never OUTRIGHT confirmed, just say he is younger than he looks. Or, y'know, just have him in earlier on the timeline.The main reason I think many people support and hope for a clone type solution is the fear of Amy being permanently replaced by Viola. Which was a nightmare the last time and is a legitimate fear.
Amy is not being shafted
