It's like that with all the healers.
Embrace? Excog? Sacred Soil? Sorry, party only. Pls spam Lustrate on the ally.
COpp? Earthly Star? CU? Lady of freaking Crowns? Sorry, party only. Pls spam Essential Dignity on the ally.
Even WHM only gets 3 options without dipping into hardcasts.
On the other hand, I get it. Alliance raid fights usually use only one tank. Imagine how hard bosses would need to hit to not be trivialized by 6 healers' worth of mits and shields and free healing. Sprouts would be bursting into flames.
