On the topic of capships: I still personally think their guns should be all turned into slow-firing artillery. That is to say Primary turrets will basically have the refire of a Battle Razor (but with damage tuned accordingly). Thusly it'll make capship fights more tactical.
The exception being Solaris/Anti fighter guns, Flaks, Etc. Since they sort of NEED to be quick firing. Gunboats may be the exception for this, as there's a fine line between OP and Outclassed by everything, with turret steer being the balance point.
Transports/Liners will need to be factored in as well, but mostly the removal of armor upgrades in this scenario will equalize alot of things.
