Don't normally partake in the "Perk the (fill in the blank)" discussions, but looking at the K/D on Innominate's page, I noticed something interesting:
Model Kills Deaths Kill% Death% K/DRatio
Me 262 1129 149 0.62 0.08 7.53
Tiger I 4686 932 2.57 0.51 5.02
Tempest 405 103 0.22 0.06 3.89
Me 163B 300 87 0.16 0.05 3.41
F4U-4 319 97 0.18 0.05 3.26
F4U-1C 2899 1045 1.59 0.57 2.77
Ostwind 9259 3950 5.09 2.17 2.34
Ta 152H 269 126 0.15 0.07 2.12
Out of all the vehicles with a K/D greater than 2, the Osty is the only one that isn't a perk ride. Just food for thought...
