I don't know what Mal had planned, but I've just about always thought that bots need personalities. Like...
One parameter in the bot file to define the bot's bias between moving(attacking) and camping(defending ambushing).
Another parameter for Courage
(i.e. agression bias as a function of the number of friend over foes in a area sample near the bot).
A third parameter for Death Wish (bias to moving alone toward objective and foes when health is below 20% vs camping/waiting for more team players).
And a fourth parameter about a bot's focus on class specific behavior (healing, building/blowing, supplying and satcheling. Soldiers would have zero for this parameter.

Then add some scripting options to give courage boosts, aggression boosts and objective focus for short periods of time triggered by map milestones and time clock.

Of course testing would get very complicated.
