no, the devices i have researched are capable of far more than just modifying your rate of fire. Ever seen a guy hopping around - every time he hits the ground he's back up in the air. you cant hit him because he is Never in one place. But he has aim assist and can hit you easily. That's just one example of what these devices can do. I hate them. There are wall hacks (for COD at least), grenade mods (like throwing C4 AND trip mine at the same time - very deadly), God mode, etc. If you are really determined to cheat instead of develop real skills the devices are out there, but i will report anyone i see cheating.
