first, agrees with doc.
second, if you are good, you are good. being a good virtual pilot would seem to understand ACM, and you should know what certain planes can do better than others, regardless of what you fly. i would think flight enthusiasts would enjoy flying the earlier versions of their favorite planes, wouldn't they? what's wrong with the 51b, 190a, 38g's (besides the 38 is porked) being super uber in a spit16, or la7 isn't really saying that much, they are 2/5 of the best planes that are unperked. why can't you be super uber in a spitV and and la5? spitV turns well, though low ammo. la5 accelerates quite well as i recall.
i don't think it is should be considered penalizing, just balancing. late war planes dominate the MA. the problem i see with RPS, is hoarding. it is always nice to have the option of upping a 262 to fend off a huge attack.
dunno, could be just me:)
