Yep, that is really the only big appeal of Bene nowadays. Being able to fully-heal while in Cleric Stance, something the other healers don't have. I don't think lowering the cooldown is going to make it any more better than what it is though. Even PLD Hallowed Ground is not appealing nowadays. Big deal. they don't take damage which means free healer DPS for those seconds.

Living Dead and Holmgang are no big deal with AST/SCH either.
