Inconsistent melee lunge in Halo 5

Anyone else feel that the melee lunge is really inconsistent in Halo 5? Sometimes it feels very pronounced like in Halo 3, (which is great), but other times I go in for the melee and I don’t lunge towards the enemy and end up just swatting in the air in front of them. More an annoyance than anything, but I’m curious if any of you have experienced the same thing?

Yeah that happens to me from time to time, just a bit unlucky thats all. I only melee when I’m within a foot or two from my enemy, I don’t really try to 'lunge in.
