The thing is that piloting tools are already pretty cluttered, and I feel like this would actually be a really powerful tool for certain long-range ships, so they should give up a gun to compensate.
The three shots are to give the cloud's appearance and distance more variance, so you can't just estimate the center and blast away.
The projectile nature allows using it to support allies potentially, though it shouldn't be absurdly long ranged else it be a bit too silly.
As for a tag, it is supposedly firing what is basically a pipe bomb, so it could be rather damaging. At the same time, it is no flare gun, and can be used for its intended purpose much more easily. 50 shatter should be noticeable enough, though it may be hard to miss a literal cloud erupting in front of you.
A more thematic effect would be a slight push upon the cloud forming, making it more disruptive and disorienting, though that might encroach too much on the minotaur.
Point is people want to make clouds. Clouds are fun. Except the sand clouds. Those are not so fun.
