Why did 343i ruin the grav hammer

Have you all noticed that the grav hammer doesn’t knock over vehicles even though in. The description it says it does. I miss the good old days where if a warthog was coming at you, you could hit it and it would go sprawling across the map. This feature made the gravity hammer worth it in big vehicle base combat (perfect for warzone). But its not there also as a side not the night blade doesn’t have the nocke back either and as a mother side for godsacke take spartan charging out of grifball it just ruins it
