So your just asking for the game to be made easier? I really see no problem with amplify, if it's as OP as you say use it yourself and you should be unstoppable right?
Not everyone uses amplify and from my personal experience most of my deaths come from MY mistakes, such as not checking a corner, poor accuracy, etc. not some overpowered perk being the sole cause of my every death. In the nicest way possible I think people should look to improve their game, not come up with excuse after excuse of why they die, "this game is full of campers", "the MSBS is overpowered", "amplify is the so OP omg COD Ghosts is over".
Now I'm not saying the game is perfect or flawless, but many of these "issues" can easily be overcome with right perk set-up and a thought out game strategy.
