Help the poor ANODONTO!

So, I was playing with my friends ano, and then these two hatzes came an did this hitbox thing killing us. Basically, they precise movement on top of the ano while flying and peck it(or I don't exactly know what ability it was, I just know that it was a head attack) meanwhile the ano can't get them in ANY possible way, and they can without getting hit! Is there any freaking way to hurt them as ano when they do this? If not, it should be something to fix. It's very annoying and unfair.
