Everyone agrees that the CAS GAU is just…shit.
Its fun shit but it is, sadly, still shit.
I propose the GAU should strafe in a straight line with minor deviations in a 3x6 area of effect.
What do I mean by minor deviations is a 15% chance that a bullet hit out of center line:
With a Fire mission with 1 GAU firing on gimbal 0 - 0 - 0 (That is, for those who dont know, Fire-Cooldown-Fire-Cooldown-Fire) from west to east and lets stay 18 bullets each fire, 3 bullets per tile in one Fire command:
XXX-XXX-XXX-XXX-XXX < – This is north of center line 10% chance of a bullet hitting here
YYY-YYY-YYY-YYY-YYY < – This is the center line 80% chance of a bullet hitting here
XXX-XXX-XXX-XXX-XXX < – South of center line 10% chance of a bullet hitting here
This way, with one GAU, if you hit a xeno with the center line you can damage more than the clusterfuck it is now.
With FOUR GAU, which is maximum BRRRRRRRR, and a full fire mission with a tight Gimbal you might kill or seriously injure something.
It loses the building destruction capabilities it has now and becomes more dificult to use effectively but should be better than what it is now in damaging or killing anything more than a lesser. It would also make more sense.
On a Strike, instead of a Fire Mission, it should fire in a 3x3 or 5x5 square, since its not possible to give a direction to it.
