Power of Axe
"Push away enemies whose health are lower than 230, lasting for 7 seconds, and 120 seconds to cool down" -Description in-game

This skill used to push away all units and it was the main reason to buy Axe Warrior. As you would push back enemies behind the Hero, Axe Warriors could get a hit or two

Now, it's near worthless. Axe Warrior will one-shot most Tier 1 units and kill in two hits most Tier 2 (Tier 3 and Tier 4 all obviously have more than 230 HP)
