Sometimes I don't understand the tactical AI's choices at all. For instance, I was attacking Solaris' indy province of Knights of the Chalice + Flagellants with a couple of Sauromancers and Shamans and some chaff. The Sauromancers were scripted to cast <Communion Master, Storm of Thorns, SoT, SoT, SoT>. Come battle time, the knights charge my lines, my mages cast Communion Master and then, when the knights are seven squares away, cast Storm of Thorns as scripted... at the flagellants 18 squares away! I was relying on SoT for its stopping power, and it's not like there was any danger of friendly fire. Totally baffling to me. It turned out all right, and in fact on the fourth round of battle my mages took some time out from shelling flagellants to tie up some knights, but there are times when I don't understand my mages at all. I'd have them executed for incompetence but there's no disband command...
Edit: actually, now that I think about it, I bet the AI was optimizing for damage output. Since Knights have high Prot, they hardly take any *damage* from the vines, so the flagellants look like a better target. I suppose next time I expect a situation like this I should script Tangle Vines instead even though it has a much smaller AoE.
