I've been playing MP since Shogun 2 was released and in most of my battles I have used 6 units of Katana Samurai, and usually 2 Bow Ashigaru and 2 Yari Ashigaru. I can't count the number of times veteran slots were unlocked for my Ashigaru units although they are fodder and usually get slaughtered, yet never once did I unlock a veteran Katana Samurai unit Even when they get a huge k/d ratio on the battlefield.
Does anyone else have this "problem"?
