I mean, in Generation Hope, she came off as funny but tragic, and I thought there was more going for the character, but ever since Schism and Wolverine and the X-Men, she's become so one note. "We're Monsters now!" she says repeatedly with a grin on her face. It's just frustrating because she went backwards in development.
Also, I really hope she's not the only Light to stick around post AvX and such. That would bug me.
