I have this weird feeling but I sort of agree with Krusty's logic here. Ord/Gun packages should have different eny values all together. For example on the P51-D you should spend perks having the bombs/rocket mixture, however for the 109g14 sake of the arguement - the ENY should be lowered if you take the 30mm option rather then the 20mm. Fact is on a snapshot you only need to land 1 tater to kill a fighter with a 30mm, 20mm however it won't down a fighter.
Standard armament for the P-47 is a classic example, very few 47s flew with 425 rpg. Instead of perking this, make it a lower ENY, standard ENY would be the 267rpg.
Its not going to change the balance of the game, the P-47 isn't a perk plane, however the armament factor is.
However, I tend to stick to historical values, Aces High does not follow these lines - HTC needs to make money, there is a balance of arcade and simulator/historical values. We have ICONS for a reason, the learning curve is already to steep. To keep it simple HTC is balancing the game best he can.
Look at the P-47-d11 ENY, if we start perking the gun package, who does it effect? the 12 people who actually fly it? But then again it still won't make sense if you force someone to take a 2x 20mm version La-7 vs a 3x20mm La7.
I still want to exend the ENY system from 40 to 60, however this is an entirely different argument and one I have seen have clear sides of it. My reasoning is simply to reward players who fly OLDER planes, while Aces high is still dominate in the Late War Arena.
Call me stupid but I have more fun trying to land 2 kills in a p40 then 2 kills in an La7, while most newer players try to land 2 kills in a La7, it took me years to learn, with a larger ENY system it allows more tweaking of this perk options.
