In summary:
Airbases should be the WAY air should move NOT air GROUPS.
This is because airbases have ALL the air types IN ONE PLACE. So, no more JG51 then KG 23 THEN etc etc to find all the planes in a base- which if I had 2 lives, I guess I might be willing to spend my LIFE ON.
This present "airGROUP" way is sub optimal! Intuitively the position of the planes (i.e. airbases) is how one directs the traffic so to speak.
In the air phase is almost impossible to note WHAT HQ is there (it is like grayed out) so that air planning can be fine-tuned. Instead, most will just revert to generic formula such as AGN etc.. Again, people do have a life other than SORT out this !
Given the OTHER possibilities which could occur it's amazing that present way is the best one could come up with.
It really sucks the life out of this game
