Important stats for the Heavy fighter is also in that they have more weight in gaining air superiority than their smaller counterparts which affects ground warfare and CAS/Bombing efficiency (which is huge for me as Japan in the Asian land war as fewer planes to give me the bonus lends me to provide mils elsewhere). When deciding where/what - The mission efficiency works similar to saying if you have 100 fighter 2s at 50% efficiency and 100 Heavy Fighter 2s at 100% - the heavy fighters will be in battle at a 2-1 ratio over the lights which makes them spread the damage out between them better and will win the fight. Heavy Fighters work better in areas such as Africa and the Pacific War where the regions are typically larger and their range is required to gain mission efficiency. Most favor for the heavy fighter is neglected as Multi-players still typically avoid things like strat bombers. There is a fair bit out there and mindset of the differences.
