Since shadowheart is a more dex based stealthy cleric, bless and hiding is actually kinda OP with how hide has been made a bonus action and is currently a little too easy to abuse in combat. Cause now everyone else has an easier time to hit in conjunction with the homebrewed height advantage, making it that it is rare to miss. Add in that changing hide to a bonus action means everyone can do it is basically meaning enemies can not do anything while you melt them.
