I woud like to see more upgrade capability for towns and castles to build more towers or more houses or something to make them grow a bit.
And a way to make the groups be in formations b4 u start a battle so the mele stand in front of the archers and the cavalry on the sides and not everyone in just a bunch so the enemy cavalry just charges and attack my troops b4 i have fixed em.
And be able to decide where to put the troops in castle so u can have the archers in the towers and on the walls a bit away from where the enemy gets in to the castle because now they are just bunched up in the same area.
