With the latest .2 version, Playing as a Priest with 3 mana, and 29 health, HB ended turn without healing self.
HB also went into shadowform, and instead of destroying one of the opposing minions that had 2hp, it decided to double the minions health of a 2/3 earthen ring seer, which was then destroyed the next turn.
Also, HB knew the opponent had a weapon that was capable of lethal next turn if I didn't get healed or play a taunt. And it decided to play a non taunt minion nor heal, or use a card that could have destroyed the enemy minion and healed me, to prevent guaranteed lethal next turn.
