The new beam AI introduced in .7 may work better for continuous beams, but it is in some cases worse for burst beams. The most egregious such corner case is when a missile is coming in just outside the firing arc of a turreted burst PD - and the gun will cheerfully waste all its charges firing on empty space.
However, they do also seem to have some issues with tracking moving missiles; this is most obvious with the Argus PD Beams from Blackrock Drive Yards; if you install one of these to cover your rear against salamanders, it generally takes it three shots to kill a missile when it ought to be able to take a salamander down in two.
