I agree, Far Cry 3 definitely needs this. This game has plenty of room for open world/stealth/dynamic gameplay but it sells it self short with AI that robotically locks onto your location. This breaks immersion and turns what could have been a dynamic game into just-another-shooter. The AI from Metro Last Light handled this very well, instead of enemies instantly knowing your location from a single shot they actually had to look for you, I wish more developers would take note.
