I would love to see a floating perk point system like WBs had for scoring. It based the score value off of the number of sorties flown (or # of kills, can't quite remember) of each plane, so the most-flown planes scored fewer points for a kill over the less often flown planes and the less flown planes reaped large bonuses to their kills over the more popular planes. Kind of like our current perk system but without the set in stone perk values assigned to the planes.
Oh, and will the perk values remain the same in AH2 or will there be an update to the numbers?
