Air Stomp is great feature, especially on crash site when u fall from high structure, yesterday i got double kill with it. Just read some info about it, and u will learn, how to use it to dominate
Lucky stuff happens to everyone, and yes I do agree with you, Air Stomp seems a lot more efficient in Crash site than any other gametypes, but that doesn't make it usefull.
I don't know if it's a bug, or they really intended this ability to be this bad.
However, some cool stuff happens with it, at one point I tried to Air Stomp someone and it failed, (surprise) and 1 second after I was Air Stomped and killed. Now see that was awesome
