Please take away the canned death animations from Halo 4 and replace it with instant ragdoll. It’s much more realistic to watch a body fall with natural physics than it is to watch them fall with the same exact/distinct canned animations over and over again.
It’s poor visual feedback when engaged in combat and makes it less satisfying.
Take a look at the way the ragdoll system worked in halo 5 and just repeat it. It was perfect in Halo 5 and didn’t need to be changed.
