The 110 is pretty much a target, I suppose one might do alright in it in a multi vs multi environment just blowing through and cherrypicking, but I think it probably gets used for building battlin' in AH.
Unless something drastic changes in the FM, the top 3 will always been the La-7, Nik, and Spit (I suppose the order might flop around), simply because they are all around the best planes. I was more looking at the number of planes that had 1-3% of the usage each.. it used to be La-7, Nik, and the 3 Spits with 10% each, then Tiffy and P-38 with about 8%, then the rest. The rest seem to be getting a bit more use in today's arena.
Can't believe I didn't notice this the first time through... HT's much ballyhoe'd revamp of the run90 cockpit seems to have lessened its popularity some... not surprising considering you can't see out the damn plane anymore. I don't know how far back you have to go to find the G-10 ahead of the D-9 in the kill stats before the remodel... not sure it has ever happened.
