Want to stay loyal to your chess piece and stay with the horde? Have to deal with ENY. Lowest ENY plane I regularly fly is the Ki-84. C.205, Yak, and A-20 were planes of choice last night for me. I like taking a low numbers country and flying against the horde, because I generally DO find myself flying against planes other than the splixteen, lagay-7, runstang, and niki.
So, yes, at times ENY does make a difference.
