i'm talking about the change to Cascade

i'm talking about the change to Cascade / Halo and Divine Star. I understand the reasoning behind it, wow or but these are Level 90 Talents. They need to be a cut above all other spells, and it seems more punitive than worthwhile if they are given a 1.5 cast time in "any" fashion. If the trade off was a significant slash in their CD it would make some sense, but that hasn't been mentioned at all.
