HALO MELEE ATTACKS

WHAT DO YOU GUYS THINK ABOUT THE MELEE ATTACK ON HERE?

IS KNIFING TOO OVERPOWERED. AND ITS IMPOSSIBLE FOR SOMEONE TO TAKE OUT A KNIFE THAT FAST.

I WAS THINKING ABOUT THIS WHILE PLAYIN HALO, HOW U HAVE TO GRAB SOMEONE IN ORDER TO KNIFE THEM (ASSASSINATION).
HOLD DOWN THE MELEE BUTTON TO PERFORM A COD ASSASSINATION WHICH WILL TAKE 3 SECONDS TO PERFORM AND IT HAS TO BE PERFORMED BEHIND THE VICTIM.

OR JUS TAP THE MELEE BUTTON TO HIT THE PERSON WITH YOUR GUN OR FIST.
IN COD 2, IF YOU HAD A PISTOL OUT, IT TOOK TWO OR THREE HITS (IDK) TO KILL SOMEONE WIT PISTOL WHIP. ONCE WITH A BIGGER GUN.

IF YOUR GOIN HEAD UP WITH SOMEONE, I THINK TWO MELEE HITS SHOULD KILL THEM INSTEAD OF A STUPID KNIFE LUNGE AND INSTANT KILL. MAKE PPL USE THEIR GUNS INSTEAD OF RUNNING AROUND KNIFING PEOPLE WHILE THEY SHOOT U AND HIT YOU BUT SOMEHOW U SWUNG A KNIFE AND KILLED THEM.

FEEDBACK PLEASE..............
