Some ideas for the Battlefield:
Have your wonderful art team toss together a few more maps to rotate through. maybe tied to the battle aid of the war, or the month, season, random… I am sure there are more ways the teams can be arranged within the map to keep it graphically interesting. (ie, not always a grid configuration).
Allow us to zoom out just a tad bit more so we can see our whole team army or opponent army in one screen and not have to scroll side to side.
That’s all I got.
