Range 3 dread is an ENTIRELY different discussion, it would be way too invincible (and note we have tried such a thing back in the day, it was pulled back for good reason)It's way more realistic to make Dreadnoughts range 3 as well but ik they can come before arsenals which is problematic. Lowering dreadnought movement to 3 could be in interesting trade-off, since 'Battleships' are called 'Fast battleships' irl, due to their highers speed than Dreadnought type battleships.
The battleship comes at a time with a lot more high range counters, so the range at that point makes more sense
, portraying smaller secondary batteries and sluggishness making it an easy target to torpedoes (destroyers). I agree it could be unbalanceable without making more drastic changes though (like dynamic
penalty the further away a unit shoots).
