I think balance is a good idea, no point in having non perked planes or gv's that unhinge the game play. Next thing to fix is the auto ack. At D6.0 there is no way the AI gunner can know which way I am going to turn, The shells have a fixed patch once fired and that correction takes time. the fly by wire 5" shells are just plain stupid and affect game play. One other thing, proximity fuses did not enter service until mid 42, they should be deleted in EW and perhaps MW, it would be an interesting experiment as long as bomber accuracy was addressed too. No one every hit a capital ship with four engined bombers, almost all hits were dive bombers and torps.
Over all I think good tactics should be allowed to produce good results.
