^Maybe some people. But I have a couple friends who own with the G-MAL. And they can two burst kill usually without missing a bullet. In the end, it's the user not the gun.
I still use Elena's G-MAL (most people can't play without Accuracy and call me crazy), but that doesn't mean that the G-MAL is OK in its current form.
Don't forget that it was meant to be a starter weapon (unlocked from Level 1) compared to other weapons (FAL-SS / Level 50)...
