I believe the IJN torp spread should be tightened or the USN torp spread be widened. Also the time to arm be shortened because either they hit before they have armed or I have to drop them too far away that maybe 1 out of 8 will hit. I've got the Hiryu now and I've totally just given up trying to use IJN fighters. I mean they are useless and its worth more my time to have the extra torp bomber and bomber than two useless fighters. All I do when a USN carrier is on the other team is going after it and try and sink it. Don't get me wrong IJN carriers aren't THAT bad. but I'd like them to get a buff of some sort with a tigher torp spread or the USN torp bombers getting a widened thread.
People have now got some sense about how to deal with carriers/planes so the time to arm should at least get buffed as everyone and their grandmother actually is looking out for aircraft now unlike before when OBT started so the time to arm should be reduced. Not to like arm when they hit the water but maybe a 20% reduction on the current time.
You can do great in IJN CV's But this is rare. Most of the time either two Iowa's can go in-between my spread of torps or the american battleships turn on a dime or american fighters just kill me or the other Japanese carrier nukes me. the list goes on for how great (bad) it is to even try and grind IJN CV's I skipped the Ryujo with like 50k free XP. Most of my games end up with me becoming the Hiryu-class submarine.
