The problem with MW3 EMP is that you could just get 6 guys running EMP then just detonate one, then another a minute later, then another etc.
Most good teams who ran into other good teams would realise that they werent going to get AC130s and thus decided to d00sh it up with EMPS to block the enemy from really being able to call in anything useful, making the whole game boring.
But I do agree that 40 seconds is so not enough for something that costs 1300 points, 60 at least, its onyl an extra 20 seconds.
