Reasons why the computer will not cast the spells you script

[Goad]

I found out the hard way not to bother with wind guide when my Sidhe Lord, 9 Daoine Sidhe bodyguards, 4 knights and 60 longbowmen were routed by about a dozen hobugs & a mage casting mind burn. Thank you AI. I lost 30 archers, all 4 knights, and 3 Daoine Sidhe while my Daoine Lord amused itself casting protection and sermon of courage.

It's just as effective, much more reliable, and quite a lot cheaper just to have a couple air 1 mages cast aim-aim-aim-aim-aim. Just keep your archers off to themselves or the stupid mages will cast aim on militia instead of the longbowmen.
