I think I know what Strad is talking about. I have seen it using dual ACs on opposite side of a mech. What I believe happens is that if you are close to a obstacle, and have your crosshairs close enough to the edge of that obstacle, they will use the range to the obstacle to judge where the shots should converge. This causes the two AC rounds to cross at extremely close range and then shoot off at a extreme angle.
I think this is somewhat working as intended, since you really do want your shots to converge, but sometimes it seems that the game will grab and use the range to the obstacle even when you are not pointing directly at it.
I have no idea how aiming really works, but in layman's terms I think we are asking for someone to take a look at tightening up the area under the crosshair that is used to determine the range to your target.
