Since Warding glyph is getting the largest defense buff (and the only useful one), as it currently is designed it cannot work. Sorc have a near mandatory passive and 2 dps aspects, needing us to stay near full mana. The idea that we would be sitting without mana to get a defensive buff is never going to work. Can Warding functionality be changed so that we have DR the more, instead of less, mana we have? Otherwise the glyph and its buff are obsolete.
