You misunderstand my point. There's nothing inherently wrong about gypsy characters with crystal balls, but they're incredibly out of place in a game like Soul Calibur where a lot of the character design is at the very least rooted in some real-world equivalent/culture/origin or otherwise explained by connection to supernatural forces already present in the game's canon (Soul Edge and Soul Calibur). Viola and Z.W.E.I. were literally anomalies with no real world cultural basis aside from a loose adaptation of Little Red Purple Riding Hood and the Big Bad Wolf.
That's why I said if they went with a traditional Romani gypsy basis for Viola (aka her 2P), I would have been more accepting of her in the SC universe.
