I never realized the sentry gun was stupid. When I would place one it would chew up the enemy team until someone kinda got the bright idea to take it out, or just ignore the area it's watching...which was a rare occurrence.
It wasnt that it was stupid, its that it would shoot around the target before actually killing them
But they made it track people better now so hopefully that wont happen as much
