small healing spec question

[vor_lord]

In the context of Reflective Shield for raiding/instancing:

The best uses of a shield in PvE are:

• Preemptively protect against damage (preshield)<>
  
• "OH CRAP!!!!!"<>
  
• When your target is mortal striked (hmmm, should that be mortal stricken? It can't be "stricken with Mortal Strike...". Mortally Stricken? I think that's it. ;)<>
  
• Assisting when healing AoErs, especially channeling ones<>

  In none of these do I see the relatively small amount of damage added as very useful. I've tried to dream up new ways to use the shield given this ability, but without success. The DPM is not very good as a damage dealer.
  
  But for PvP -- Reflective Shield is very nice.
  
  So my recommendation is to get Reflective Shield if you PvP, and Mental Agility if you do not (given just those two choices).
