True it's accuracy isn't the best, but that's more down to the weapon. The problem with forcing them to focus fire is the range. Unless it focuses at the weapons max range it'll be very wierd with an x like shape. And even if it does it'll have the same issue at anything but max range.
At least with it being straight it's just point on or both at a target.
That or have them have a little more room to turn so you can focus fire, or choose to just shoot straight.
