Yeah most ships weren't equipped for anti-starfighter combat, save a few, like the Lancer. There's basically only one factor that determines that. Number of Turbolaser turrets, vs number of Laser turrets. That and anti-fighter warheads. However, anti-fighter warheads on an ISD were something that I believe was made up as a game mechanic, and we'll probably avoid that in favor of other measures. Most notably, making capital ships virtually impossible to take on solo. They'll all take big ship weapons to take them down. They'll hopefully have tight shields meshes, that for the most part prevent you from getting inside of them. Other capital ship turbolasers will be the only thing really capable of making dents in the shields, save one or two other tricks. So capital ships will hardly ever bother shooting at fighters, and will probably just be big objects in space except for their typically sparse cover of laser turrets. Just enough that you can't sit still on top of one, but not enough to make them a real threat to you. It's going to be about fighter combat in the long run.
