This pretty much sums it up logistically. I the content where parry would be relevant (raids) the events are scripted and good healers precast. The healers know hen the damage is coming and start their cast before it arrives based on their knowledge of the incoming damage so the damage is healed almost instantly as it's taken. Often times the parry leads to an over heal and wasted mana in that case. Also the mitigation properties of dps shouldn't be understated. Moves like souleater and cool downs like bloodbath give back health at much larger rates with higher damage output.
