With the Redeye update, I had a few chances to play around with the kukri. If you thought the katana was awful, then this knife is even worse and on a shorter range. Still, it does show the problem with the melee limitations we have right now.
I understand they were trying to “encourage reticle aiming” or some nonsense, but that doesn’t work with the M2 melee because the hurtbox doesn’t appear in the instant that the button is pressed for any melee weapon, unlike a gun where trigger pulls are instant. Tracking is necessary for melee strikes because we have to keep the reticle on the enemy for several moments until the hurtbox is active, and the kukri has such a long windup (I think it’s even worse than the katana) the enemy can blow right past it without even thinking because we are unable to track them in melee combat where it is commonplace for two fighters to accidentally spin right past each other.
The speed limit has to go on melee full stop, it slows the game down, makes certain weapons unreliable, and generally feels gross.
