I'm a returning player, made a new account, currently Iron age and I noticed that historic description is not available for any of the troops. Last time I played there was a questionmark in the upper right corner of every troop's picture which had historic information about the unit/troop. For me this is one of the best features in the game which differenciates it from the others. Every unit had a brief historic info about them. Don't know if anyone else noticed this or has the option missing like me.
