I've haven't watched either of them but I've never heard anybody that likes yuri say anything good about Cross Ange.
You shouldn't watch Witch Craft Works for the yuri because it's more of a homosexuality-never-works-out kinda thing.
Cross Ange will end in march, so I doubt it will have any yuri, and if it will have yuri end it will probably feel really forced,
and Witch Craft Works I never really expected any yuri, unless they reveal that the mothers of the protagonists broke up fo another reason and the marriage was just an excuse to hide it and they end up together, but I doubt it.
I was going to watch cross ange but then someone showed a male main character out of nowhere, and guess what? he shows up in the isle full of women and they're all curious about him ...so the yuri is fanservice and again the main atraction is a harem I guess, that's my view, I didn't actually watch it but ...nope, I don't have any interest anymore.
What I know is that the only two relevant male in the series are villains, and the reason the girls where curious is because a lo of them grow up in that island and never had seen a man, the only harem would be for Ange, but it's only subtext for now.
I know that I shouldn't watch them for the yuri, especially Witch Craft Works, Cross Ange I hope it will end in yuri but it is unlikely, I think that the opinions of yurifans would be more usefull for me that's why I asked here on Dynasty, so if possible I hope more people say something, but something tells me that this topic will be ignored by most people and will not even have 10 posts, which is making me sad....
