There are somethings that AW did right and one of them was how field damage was done. Like the example Whels gave with the ammo, if the ammo was completely destroyed at the field, cannons weren't available. If fuel was damaged, it degraded the quality of the fuel and it had an effect on your plane, the engine would run sluggish. If you damaged maintenance (something I wish we had in AH), it would effect the planes too, you may get an airplane with smoking engines or leaking fuel or damaged hydraulics.
Probably why some of the best fights in AW were for bases, I guess when there is something on the line, people tend to fight with more gusto. Zone limits helped too.
