It is plenty descriptive for a laser.
But what does a disruptor do? There is one line describing that in the submission and it dosen't explain what the devices fires (a particle stream, radiation, a bullet of some sort) much less how it interacts with a target. Loss of structural stability can mean anything from a slight weakening of something to completely falling apart, to disintegrating, to exploding. The result is that with this level of description people who use the submission won't use it in a way that is uniform.
Also, proper explanation of a submission is actually a requirement of a tech submission.
