Clips that show how inconsistent the melee is

In the first clip you see that I kill a fully shielded player with one melee. Maybe he gave his back to me but I keep rewinding it and it looks like I hit him from the front.

In the second clip my melee misses even tho I’m close to him and then he backs smacks me even tho my back is not all the way towards him.

In the third clip even tho my animation clearly touched the spartan I had no sound or damage come out of the melee and ended up dying because of it.

Here’s the video.
