FF pop isn't inflated, but Churchill pop definitely is. I think it was increased from 16 to 18 initially, but afterwards to 20, almost directly following CaptainSprice losing to AshaBlois in some tourney. Sprice only had Schrecks and Stugs and slowly got suffocated by triple Churchills. IMO Price played that match wrong and the additional pop nerf was not justified.
I'll try to find the match once I can.
Pop of Churchill is 19.
Oddly enough the pop of KV-1 is 14...
