Both Krunk and Garfuka had two adaptations. Having two adaptations is pretty imbalanced, and I don't think Garfuka has reached Krunk's deadliness (perhaps due to berserk changes). So saying that Garfuka "tapped" orc potential is not quite true.

That's like playing a four legacy (with good legacies) warrior and saying that you've tapped a warrior potential.

That being said though, Garfuka was fun and good for the game.
