If the 3.1 glyphs notes are accurate:
Glyph of Divine Plea: While Divine Plea is active, you take 3% reduced damage from all sources.
Glyph of Hammer of the Righteous: Your Hammer of the Righteous hits 1 additional target.
For existing one, I like:
[Glyph of Spiritual Attunement] Increases the amount of mana gained from your Spiritual Attunement spell by an additional 2%.
[Glyph of Righteous Defense] Increases the chance for your Righteous Defense ability to work successfully by 8% on each target.
[Glyph of Judgement] Your Judgements deal 10% more damage.
I agree that with the new taunt [Glyph of Righteous Defense] can be replaced. I will most likely swap it for Glyph of Hammer of the Righteous once released.
Personally I will likely swap Glyph of Spiritual Attunement with Glyph of Divine Plea. I like the damage reduction, besides DP replenish the 2% gain from the the glyph.
