Nooo Heavy Beam Cannons have per planet cap
What? I don't recall changing them in that way.
Or are you saying that you wish that they were per-planet-cap?
While I would LOVE to see them be per planet, I can't see that being balanced in any way at all. The only way to make it balanced would be to hit them with some serious nerfs, because they are pretty on the line as far as OP goes. However they are too much fun to nerf. So, I'm going to say, please do NOT make these per planet, because it would either make them WAY TOO OVERPOWERED, or you would nerf them too much. And if you nerf my HBCs I will find you, and it will be messy.
Also,
Speaking of Flak turrets - The old Mk I-III progress had 5, 6, and 7 hits per shot. Do Mk IV and Mk V hit 8 and 9 respectively, or still 7?
Would it be possible to fit that number somewhere into the stats or description of the turret?
This is a very good question.
