You do know there was a Sea Hurri with the IIc 4-20mm wing that could carry 2-500lb bombs? I asked for it some time ago. I think there might be some hesitation to allowing 4 cannon unperked birds off the CV's in this game. You could pull a CV right on to shore and launch a never ending hoard of 4 cannon HOers to mow everything down. Especially with the puffy ack keeping everyone below 3k. Your hoard just ups and circles above the CV to 5k or 8k and cannon vulches the feild defenders.
Anything nonperked with 4 cannons in a hoard with a 25,000 yard auto ack protected flight to the target is a disruptive game play problem. What would happen if HiTech unperked the CHog only from CV's? Most players would up in only the CHog because of the 4 cannon HO power.
