the IED do have a beeping sound, its 2 clear sharp beeps whenever you walk near them, they have a built in stalker pro perk where you can run right past them without any damage.
get out of that BO2 mentality and slow the **** down, your dieing all the time because your running around aimlessly, spraying bullets everywhere expecting the game to spoon feed you everything.
the game isn't stupid you are.
We all thought claymores were bad, IED's are so much worse. No way of knowing their there, no way of getting away from them. IED's need to have some sort of beeping sound that always plays when they are placed on the map. IED's are stupid, just like this game.
Who is this "we" you mention? Generalizing your experience to others is inaccurate.
Clearly, the sound they make and the blinking light they emit is the problem. I think your eyes need a buff,
