Y'know, something that completely never came to my attention...
...when I upgrade my horsemen to knights, or cavalry, etc., all my elites lose their training! Hopefully I didn't fudge something up here... is this standard?
I never really noticed it, but the way I see it, there might be something to be said for leaving your elite knights as knights when cavalry rolls around, and using your veterans as the new mainstay. The way combat is, a 4 is nearly as likely to win as a 6.
In a game sense, I understand it - the upgrade actually erases the old unit and produces a new one for a reduced cost - but the unit is a standard city-with-barracks issue, i.e. a vet. But it doesn't seem to make sense that my crack troops suddenly forgot everything their vast combat experience has taught them...
