I dont know why this isn't talked about more and why it isnt in the game. It has to be a easy feature to code and just makes everyone's life easier and less micro intensive. What is it?? Its a simple button that needs to be added to the factory. To allow the repeat order of a build que. For example. You want a mix of 2 tanks and one aa. You click 2 tanks and one anti air then click repeat. The factory will now build this build order repeatedly and i mean forever until it dies or you tell it to stop. Its so marvelous !!! This makes it so you dont have to que up thousands of units and spend time clicking and worrying about things that you shouldn't need to. This feature was also in supreme commander and why you haven't adopted it to this game i don't know.
There is a button on the right hand of the screen, a little arrow with a line above it, press the button and it turns into a circle. That is the repeat button, it's already there! Don't worry buddy, we got you covered.
