Eventually I plan to take over the tactical battle AI. Right now, I only do strategic but the developers working on that will soon be working on a different project so I'll be jumping in there.
I've been getting familiarized with the system. A few decent tweaks would go a long way.
Strategically, the AI does use magic, A LOT. Mostly for buffing. I have also been working on it over the holidays to make them do more offensive type spells too.
