I don't know if I would call it an additional problem or the root cause of the issue. Though I suppose it is telling that additional works like Hollow Atraxia only cemented my opinion of Artoria. And Fate/Zero for that matter.
It would help, that's for sure. Though honestly, Artoria is the only time I feel the 'was secretly a female in history' plot point was actually used well. Atilla I'd say is the absolute worst and even comes off as vaguely insulting.
Maybe Nobbu as well. I mean, I laughed so hard at 'Real Deal Nobbu' in this GudaGuda. And I suppose we could only have that because of the whole making her female thing.
