The I.E.D. has been nerfed twice and as far as I know the Claymore never was. I think players would get mad at the claymore but wouldn't complain so much about it because of those easier to spot laser beams. The I.E.D. has a small blinking light which is really hard to spot and, similar to the C4, could be placed anywhere(ceilings, in objects, walls, etc). The Claymore could only be placed on the ground so you knew where they would be. I though in MW2 they had it right giving you two of them. Although being able to replenish them with scavenger did make them OP. I would say two Claymores and no replenishment of them with scavenger would have been perfect.
