Great to have had news about the new fragment champion early. :)
If she didn't require a second champ to fully enable her she could be really exciting, but as she stands it would be easy to see her as only a small step above any epic defence down champ, but harder to book to make fully useful.
However, it's great to see a champ with defence down both as an AoE as well as an A1 single target, which could provide useful utility against bosses - none of the defence down champs in my roster have both, so there may be use for her there. Additionally, she could make for a great campaign farmer with her two AoE attacks.
Have to admit I'm more excited about Alsigor and the other new champs, even the epics, though. :)
