After further discussion about the change in patch 2.3 which adds diminishing returns to silencing effects, we've decided to revert the change. Though we do feel that being chain school locked is a problem and plan to address it at some point in the future, we weren't comfortable with the amount of testing this particular change received.

I really hate to say this, but it almost looks like these forum "revolts" are working. Earlier in this patch cycle we had Paladins making thread after thread about threat reduction, and they got it. Now, Shamans have beat the stuffing out of their own little corner of WoWdom, and poof, here's the change they hated so much removed. Is this really a case of the squeaky wheel getting the grease, or is it more that the change was bad and that's the cause of both the revolt and the repeal?
