I agree, the icons are far too generous in AH's main arenas in more ways than 1.
I've asked for HTC to "test" things in the MA for a tour at a time for over 3 years now. I doubt they will change their ways, they know best.
I've suggest icon range changes (for both gv and aircraft), burn rate changes, a differently tiered fuel system (results at 2nd fuel tank destroyed), a tiered ordnance damage scale (results at 1 ord bunker down instead of the "all or none" system AH currently has), change up the amount of dmg needed to destroy OBJ, etc, to name a few.
