@Rexfan1333 To me, it adds more to her character when she manages to learn new things on her own. Again, it shows how intelligent, focused, and determined she truly is. It's quite an impressive achievement to make and really shows her true colors. That's just me though.
Considering that Joe Kelly stated on his AMA on Reddit months back saying that he prefers Gwen to be a human sorceress over Gwen being half Anodite, it's most likely (and hopefully) that she's going to be fully human.
