The AI is better since a few patches (at least it avoids to cast fury spells on archers and mages -if they are not in the middle of other troops-) you should try to use them more often.

ps : the only remaining problem is creeping doom the AI likes to cast it a lot, and it's one of the worst possible use of gems. It may have a niche use if you absolutly need a lot of morale 50 units in one cast to avoid retreat, but out of that swarm is far better. And if you don't want morale 50 units, summoning an hundred of them can be a real problem, Creeping Doom is a spell killing your own mages when you lose the battle, as they retreat too late. I think it should be added in the "spells only used if scripted" list (or changed a lot).
