I'm not sure what "higher or lower in consideration" means. As near as I can tell, the spells the AI tries are given ratings based on their likely effects. My assumption is the way to change this would be to change the weighting of the different types of effects: direct damage vs stun damage vs protection buffs, etc, etc.

Would suggestions like:
Lower the weighting of battlefield summons.
Increase the weighting of the path booster spells.

count as useful suggestions? Because I've certainly seen them before.
