Used the Air Strike for a while and then switched back to stock and now I'm better than ever with it. Unlike the Direct Hit, since the Air Strike has a reduced blast radius and no extra speed you have to be more precise (and even then because of how bad the air strike is due to said reduced damage radius you still probably wont kill the person) you benefit from using it for getting better at aiming since you're forced to. I was already good at landing my rockets, now I'm even better at it. Also helped me use the Air Strike's aggressive playstyle while using stock.
