Your saying your dropping healing x2, mana totem, blessing kings (sanc on the paladin), and your warlock has replenishment. Yes this is the optimal efficency. Even with 1/2 Spiritual Attune and Plea your paladin should be in excess of fine without a healer.
Wish there was a way that made blessing of wisdom and mana totem clearly not work visibly so people didn't run around trying to use it.
