The premise of this thread makes no sense. % Fun to fight.....What the hell does that mean? does it imply that planes in the 10%-Fun-To-fight-vs box are less fun to fight than planes that are in the 90% box?
P-38L is at 10%-Fun-to-fight. Which is less fun than fighting a C-47, or a P-40? That is rubbish on its face. And since the whole perk idea is based on the validity of that metric, the whole idea is rubbish.
