Now, I don't know about you, but in my games I will see Druids spend an arm and a leg to never deal 3 damage when they cast Wrath. They are devoted to drawing that card off of Wrath.
As for whether this card sees play over Feral Rage, I think it's strictly better if Pirate Warrior is no longer meta. You won't need the 8 armor option as often and gaining 3 armor is well worth losing one damage. Bash saw plenty of play after all, and that was in a class that had 2 of Fiery War Axe.
It's also possible this card has been printed to replace Wrath entirely and allow druids to run Prince Keleseth.
