Major thing was that you could mount this thing on any ship, as it was classified as level one gun. Like Justice MkI, ridiculous.
That was my fault of course, I should've checked and re-checked the code taken from another mod ten times before releasing (the issue with chainguns had the same cause). I actually did reduce the power of a Swarm, especially its power agains shields. But overlooked the issue with its classification, unfortunately.
Why did I release this quick fix? Well, imagine a middle-class ship like Crow (capable of equipping level 8 guns max) with lots of gun slots - Crow has 8 for guns and 2 more for turrets. So, 8 swarms plus one more in a torpedo slot. What will be left of a more expensive and sophisticated ship after it engages this Crow? Dust, dust...
