Most map you just spawn in front of the ennemi so the game play resume to click and wait till a ship get destroyed. With these maps design spawning first is a death sentence. Make map with more place to hide, make naval battle like naval enduring confrontation and people will play this game mode alot more
If you want to hide behind rocks then you should play tanks.
Only thing to do with naval is stick to EC, like sim air is or helicopter battles used to be. You cant make regular RB battles 2 hours long.
Ships with ~10km range dont work on regular maps.
