3/3 Imp Conc Aura - Worth it for PvP healing?

Like the subject says. If so, do I take the points out of Toughness, Shield Spec, or Imp HoJ?

If you do a lot of PvP and have troubles with priests/self-heal then spec for this, otherwise it is too situational imo, as those few bosses that actually do ae-silence can be dealt with otherwise, and the resist chance is completely random anyways.

Got as far as this: http://db.vanillagaming.org/?talent#sVxurgotVMtc, but trying to figure out whether to put the final 3 points in Imp HoJ, or Imp Conc Aura.
