How about removing the cool down entirely and making it only return the same amount as a heavy attack, or maybe heavy attack plus a little more to compensate the cost to cast. This would essentially give a vehicle for the healer to heavy attack during low maintenance parts of the right and transfer the resources they gain to the tank and DDs. That or change one if the guard morphs to funnel resource regeneration to the tank.
