Lusche's usage pie chart is interesting. The most capable unperked fighters from the USAAF, RAF, IJN and VVS have roughly similar usage and take the 4 top slots, very nicely balanced I would say
The one thing that stands out for me is how far down the list the most popular Luftwaffe fighter appears - 190A8 in 16th place (its safe to assume that the #12 110-G is mostly being used as airbourne artillery rather than as a fighter). Were the 109s and 190s really so hopelessly outclassed in the late war, or is it just reluctance for AH players to fly Lw aircraft? Despite their (artificially?) high ENY values.
btw unperk everything and you will pretty much only see Tempests imo
