On the battleship and carrier mentality, keep in mind that, at least in the beginning, the carrier was not seen as the centerpiece of the fleet as it is now. It was dropped in the water to protect and escort the battleship. As the war progressed and the power that aircraft possessed was demonstrated, the roles began to shift. As far as the game goes, if aircraft were given the power they had in WW2 as far as dive bombers and torpedo planes had, there are those that would take a fleet of nothing but carriers all the time and flood the air with planes. IMO, keeping the aircraft toned down leads to a more balanced fleet composition. In VaS, you can only target aircraft with AA guns at a short range. If you walked into a tournament and someone took 3 carriers and filled the sky with planes, unless you did the same, you would pretty much be shite outta luck. A smart player would launch planes early and from far away, never risking the carriers. The planes would kill the capital ships. As it is now, even if you hit the plane with AA, there is a chance for a dodge. Spotters can't shoot down aircraft and you can't change the plane loadouts on carriers. Also, planes are far faster than any ship in the water.
If we lived in a world where players wouldn't cheese the fleet lists, we could power up the fighters. Unfortunately, for every system out there, there are players that will cheese the lists and make the game not fun, thus killing the player base. I like VaS as is. It has some quirks, but I will take those for the speed of play and simplicity it has. If I want the detail of plotting my torpedos with a compass and ruler (been there, done that), I will play a more detailed rule set that will take all day to play the same encounter I can play with VaS in an hour or so.
Just my 2 cents on the rules.
