One issue I run into in Elemental is that as I begin taking cities from other players (ai) I quickly get bogged down in my standard build in each 1. I build buildings x,y,z, produce a few units and then ignore them because I have no desire to worry about the piles of cites i will end up with. It would be very nice if i could set a standard build order that all of my cities would work towards. This would allow me add a building or 2 to specific cites while ignoring clicking the same combination of buttons 50+ times as I take cites. Honestly I wouldn't mind seeing conditional statements like If food > x then if Max pop < next upgrade Then build house else return to build order, but I admit most people would find this to be a bit odd. (though it would give you the ability to build cities more or less exactly as you want to without having to worry about them at all as long as you took the time to generate a good build system.) A single screen to control all your caravans would also be nice. I hate having to click all over the map to send caravans.
Currently I just get too bogged down in maintaining my cities and end up totally ignoring them/being weaker.
