Specifically in the case of lasers, we don't like the approach because little dots flying through space doesn't imply a light speed weapon, which by definition a laser has to be.
Mhmm. Even ignoring realism, if it looks cooler... why not?

What I'd like to see from larger battleships are perhaps a slower fire rate, but more consistent and constant than the bursts that is in now.
Well, I like higher fire rates, but agreed re: consistent/constant bursts. The "fire 15 round bursts every 6 seconds" that some of the ships have right now doesn't do it for me. The Kols in those videos are throwing 10 round bursts every 2 seconds. A bit better, but not quite what I want in the end.
