This is also a tiring strategy. You take a squad of infantry, slow but powerful (like ogres). The AI constantly blinds them instead of attacking someone else. These slow units stand there, blinded, while the fast units take down the AI. And even if they run out, the tanks will remain untouched.
Also, the AI does another silly thing: it blinds, say, ogres, then removes the blindness with a dispel magic spell... then blinds them again...
In short, LOL.
