Warrior - Leap Slam + Boneshatter

Typically, I'm always able to Leap Slam enemies and it will reduce it's health down low enough for me to clear them with Boneshatter but i believe Leap Slam sometimes bugs out.

There are times when i Leap Slam a bunch of enemies and it seems there is no damaged inflicted. I thought maybe i missed an attack so i leaped on the spot a few times and discovered. Enemies' health does go down just by a tiny bit and i wouldn't deal the right damaged to inflict low health statues to them.

Usually after engaging in a fight and rolling away to dodge damage and rolling back to low health mob always cause a miss for boneshatter on low health enemies.
