The AI has noticeably become less intelligent compared to the original. Previously, it used mass spells and caused trouble, but in 3.1, it has only one goal: to cast "Evasion" on everyone, even though this wasn't the case in 3.0.
And if you need to distract the AI from archers, simply cast the same "Evasion" spell on some tanky unit like an armored knight, hydra, zombie, etc.
