I use it as anti-air all the time, but you need to be careful with it as it can be pretty risky against some characters due to its relatively slow recovery. From my experience, I wouldn't use it against a Kitana, cause if they do a fan mid-air, you may get punished after she lands (Liu Kang too). Someone with a teleport may be looking for it and might get you... I think Cyrax has gotten me a few times with it. Against these characters I always try to use d1, and I'm trying to incorporate standing 3 into my game as well.
