Ive noticed a major downside to making buffs largely useless in AH is THAT was the reason a lot of high-alt fights happened....majority of buff now fly in mebbe 10k, to make sure they hit SOMEthing, and since that started, nearly ALL fighting is 15k and under---Id LOVE to have SOMEthing change here to make hi-alt fights (and thus hi-alt attributes of your plane more important) more numerous. Nothing like a 25k P47 dueling a 190 or 109
