What changes are you seeing, Fur? The tooltip still says the above and the patchnotes at http://www.worldofwarcraft.com/patchnotes/ says :

Guarded by the Light: This talent will no longer cause Divine Plea's duration to be refreshed by using Judgement of Wisdom, Judgement of Justice, or Judgement of Light.
That seems that it will still refresh, just not off judgements? I thought there was a major nerf to it posted somewhere, but it's not listed in the notes, unless it's hidden elsewhere.
