Well thats a real shame as it's a complete waste having these ability's simply be there but never get used or rarely work. I'd rather have libra removed. It's just taking up a space (not to mention, completely 100% useless for anyone who plays with damage displayed on the screen...)
The job has that feeling of being half finished then forgotten with these functioning as they do.

I'm mostly surprised that SE creates new content before fixing flaws in existing content. That seems a little backwards to me.
