Something that bothers me about Blade Mistress Morgana is that for all the effort they went to make her part of the Steel Valkyries line of skins, what with Aether Wing Kayle having a line for her in that skin...there's nothing there that signifies Blade Mistress is part of that universe. She has the exact same effects as base Morgana, from her recall to the abilities she uses. Literally the only thing distinguishing her as being in a similar universe is that it looks like she's wearing metal, and even then it's too flexible to really fit in. She's just a literally edgier Morgana.
I also agree about Exiled Morgana, given that all that's unique about her, aside from her model, is her auto attacks being red, which is incongruous with her abilities still being purple.
Ironically, I was okay with Sinful Succulence Morgana having no new aspects, given that she's just Morgana who bakes...but I will not deny I'd love having some cookie aspects to her abilities, even if they're relatively subtle.
