The first edition of Battlelore did have a hero expansion. It would be awesome if we'd see heroes in the second edition. Heroes that upgrade your infantry/archers/cavalry by replacing a single miniature and adding an extra buff to the unit. Extra dice, rerolls, regeneration or command abilities on nearby units are a few of the possibilities. The expansion could have named heroes for the factions or general heroes usable by every faction, like in the first edition.

In time, multiplayer rules would be great too.
