I disagree with your premise that MIA is so close to useless that it shouldn't be used. If treated properly, it shouldn't be reducing your map awareness, only reducing the amount of the map you need to be worried about and thus actually INCREASING your map awareness. It's usually fairly easy to keep track of whether an enemy is leaving lane of just hiding, especially with my favorite item and various champions' brush-checking abilities.

I don't consider MIA calls to be a "LOOK OUT ENEMY INCOMING" but a "I'm not sure where the enemy went, keep an eye on your brush." If you know where the enemy is, you don't call, and you let people know when the enemy returns to your awareness by calling "re".
