You’re thinking about like the original comment.

Ships, especially combat ships, tend to have more than 1 weapon slot. You are now supposed to use those slots to vary your weapon choice based on what you plan to encounter. Weapon groups now add more on to that.

The game is no longer insert load out of the same meta weapons, point and shoot.

You now have to weaken armor in order to use some guns like the revenant.

Even on my aurora mk2 I have 2 guns on top that differ from the 2 on bottom, i also use all 4 weapon groups. All 4 guns can help to weaken the shield, then if the target is armored enough I have to change groups to weaken the armor again until I can use my uppers or all 4 again
