I definitely think for game balance that Melee should be potent, otherwise people would have no reason to ever use it. But one-hit-insta-kill is maybe too much.
Here is some ideas I have come up with:
-stabbing with a knife causes damage and stuns but need to HOLD melee to make it a fatal move such as "stab in, then slice open" unless you aim high and hit in the neck or head. Otherwise two knife jabs should be necessary.
-non-knife melee such as whack with rifle-butt should not insta-kill but have a stun grenade like effect; sending the enemy spinning back with blurred vision unable to shoot, you you can reload and shoot them or hit them again - in the cranium - to finish them off. Damage is good for a "finishing move" after shooting a few times
-(borrowing from TF2 charging-targe equipped Demoman) melee can insta kill if you are sprinting into opponent and press melee at the right moment
-melee from behind more deadly, ask a Doctor how deadly it would be to have an 8lbs rifle but slammed into the base of someone's skull. You're going down in one hit and short of immediate medical treatment you're never getting up again.
BTW, contrary to what movies depict getting knocked unconscious from a bash to he head is pretty fucking deadly, about as deadly as passing out from blood loss which is how most die from gunshot wounds.
Small note on knives:
-they generally create worse wounds than say a shot from a pistol or submachine gun, as a blade is wider than a knife and can penetrate about as deep.
-knifes can penetrate kevlar vests that most pistol rounds cannot due to the amount of force on such a narrow knife tip.
-human fight-or-flight response favours attacking with a knife (brute force "punches") more than guns (calm and carefully aiming)
