Yes for the perk icon change.
Yes for lowering the general perk cost level.
Yes for perking 109G10, 190D9, La7, P51B, P51D and Yak9U for about 5 perk points each. To compensate for the "loss", a 109G14, LaGG3, La5, Yak7, Yak9 and an Allison Mustang should be introduced to AH.
In my opinion, the perk point system is a great concept but has to be used more effectively than it currently is. If the "general public" would be flying mostly mid-war planes, the late war perk planes would really give a bang for the buck. Of the current perk planes, only the 262 and C-hog are really worth the investment, imho.
Thanks,
