Oddly I kind of feel like that is a good thing? In a few ways.
I feel it provides more dynamic gameplay in that it is not just one shot and done. It creates a staging effect in combat that forces players to react different when getting hit; this moves the gunplay through a number of vehicular and on foot stages rather than ending it with one shot. It allows both players to have more facets of gameplay.
It also leaves a space for other hard damage guns like LMGs to not be left in the dark.
Though I am probably over thinking it and talking out my patootie.
