Here's a few of the changes that I've heard or seen (in PvP vids). This isn't official information, by far, and it would be best to treat it as such. There's definitely a good chance I might be wrong in regards to the following:
Light of Healing - Dash cancellable at any point (currently cancellable only after first pulse).
Tears of Goddess - 5 tears instead of 3, the other two tears drop between you and where the 3 tears normally land.
Dodge - Guaranteed cast, even if you get hit during the .25 second cast time. Possibly even higher bounce.
Moon Bind - Dash cancellable (like Tears. You need to dash backwards).
Imagine the possibilities once these changes are implemented!
