Speaking as person who does nothing else than battleship PvP, I can say Battleship PvP doesn't need an overhaul. There are a few things that aren't optimal, as for example the fact that sniping weapons are less efficient than spray&pray weapons, or the fact that battleships have no weapon type that is designed to counter battlecruisers, meaning all you can do about them is blindfiring at them, or the fact that the Sci-Data codenames for snubs are generally better while the Sci-Data codenames for battleships don't break the Pulse/Primary+Hellbore meta and only work well for non-duel combat, but those are rather minor issues that sort of are acceptable.
