Edit:
Disruptor Bomb should only target units with shields ACTIVATED. Why? Because it can’t damage anything else.
As of right now it continues to fire at the same ship after it’s shield is disrupted.
According to cliffski, the disruptor bomb will only fire at targets with shields, unless there are no shielded ships in range.
The problem is it will continue to fire at the same unit after it’s shield have been disrupted.
Okay. I see how that would be very bad.
This sounds like a symptom of the “waiting too long to find a new target” problem that Cliffski was noticing regarding fighters. I think he’s going to fix this, if the upcoming patch doesn’t already address it. It was discussed early in the AI Thread, although the example there was fighters rather than disruptor bombs.
