Could dedicate all resources and structures to give high energy shields and no weapons at all and just ram things to death with a purpose built ship?
After all it's shield v shield/hull. It's about other physics perhaps.
Either your shield stays intact and destroys the other ship, or it fails and you get destroyed. Each engagement will guarantee a death. Pretty cool.
So it would be worse to ram slowly and bounce as it causes motion damage to your hull, but if you ram at supreme velocity one ship or the other will disintegrate and the successful ship will hardly feel anything, like bullet through butter. Size/mass of ship shouldn't matter. A tiny ship could pass right through a vast flag ship of the line.
I dont know the background to shield technology, maybe it could work.
