Well,the first thing comes to mind is area fire(z-fire in sp speak)
Imo as the AI will never use this ever,you should limit it to ONLY use if fired upon from an suspected location, to suppress or locate the hostile unit.
What i mean is if you z-fire on a suspected location they sometimes will reveal themselves if they happen to change stance.
That said,
I think Excessive z-fire against AI, is very gamey tactic and a major boost to human and in also PBEM.
