Another thread in this forum reminded me of something that has really bothered me about Paladin defenses for a while: we have no baseline shield skills of any sort. When a druid or warrior goes defensive, they actually gain some new moves, when a Ret Paladin does, we get a sad 5% block and some armor. In pvp this basically often leads to a slow loss for you team since the Ret gains nothing significant by going defensive and so the other team's pressure continues to be difficult to handle, while our damage is greatly nerfed making it very difficult to turn the tide of the fight and put the other team on defense.
Of course, I would rather not see Ret get too many significant shield skills, because then Blizzard would expect us to use a shield often and our defenses would be designed around it. Perhaps a baseline inferior version of Shield of Righteousness, which keeps some of the elements of ShoR such as the stacking WoG buff, and perhaps part of the damage reduction effect, could work. Another simple solution would be for TV or CS to gain some sort of defensive buff while a shield is equipped, such as perhaps shielding the paladin for some percentage of the damage dealt; this could be a glyph or Ret passive.
Anyway, my main point is that our shield being a stat stick that does not alter how we play is questionable design both from a tactical point of view and lore point of view. It feels like an awkward gap in the design of the class. What would you like to see Ret gain from equipping a shield in emergencies?
