Just a simple request. In vanilla WC3, AIs do not have the ability to use neutral/taern heroes at all. This was temporarily solved by the modding community which developed Advanced Melee AI back in the days.

But with Reforged on the horizon, odds of extremely old tools like that mod breaking~~is pretty high.
I believe the Classic Game team at Blizzard would be the best candidates to makes this happen. It would go a long way to spice the game up and make AI games more interesting.
