A couple tours ago I decided to see if I could get a good rank, and finished in the top 10. It wasn't so difficult to do in terms of technique, but it requires a laundry list of chores.
The biggest adjustment I had to make was
capturing fields. Normally, I could give a rats rear about base capture, but you have to do it if you want a good rank. Now, let's be clear, that base capture is required for a high rank has huge implications for how people will play the game. To my mind, it has a negative impact.
Another adjustment you have to make is for bombing sorties. You don't bomb when there's much of a chance that you might get shot down, that's terrible for your damage/death score. Surprisingly, I think this has positive implications for gameplay if people wish to chase rank,
provided that something is done to make the strats meaningful. Otherwise they should be removed from the game.
Lastly, to get a good fighter score we all know it helps a lot to fly where there are friendlies nearby, and where the enemy is at a disadvantage. Base defense is a no-no. Ironically, to get a good fighter rank I had to make the adjustment to die more. Landing too many sorties is bad for kills/time, so if I could get an extra kill here or there by going suicidal it was the right move now and then. Now think about that one for its consequences on gameplay.
