I wish the TA had a special area to teach the 5" guns.
My idea would have a ship with formations of drone bombers flying to intercept, approaching at various altitudes. One could get into the 5" there, and have that 'cursor' there to show where you need to fire to hit.
Try as I may, I just can't seem to hit level bombers against a CV when they get above 6k. Sure dive bombers are easy, but put them level at 6k plus, I can't seem to hit them.
Problem is in the main arenas, when you fire the 5" guns, you can't tell when the 'puffs' of smoke are from your guns or the game generated puffy ack.
