I have an idea for AHII. Because we are getting closer to RPG, there is some RPG ideas which can be very nicely be used in ToD.
Make your plane a factor to care about. For example, you get your carrier points. You can spend some for ordering your ground crew to tune engine additionally, which gives you more HP. Or to filter mg oil, so less jams. Or to polish your plane, so it is faster. You can tune your plane to something better this way, but if it is lost or badly dammaged, you lose it all and have to start again.
