I think it would be nice if we could customize our formations. (e.g we can change formation from 4×5 to 20×1 or 2×10) It just adds more strategy to the game.
Also, I like how we can select troops with number keys now. But it would be even better if we can select multiple troops.(ctrl + mouse to drag a box around troops and select all the units inside the box.
And if we can save those selections. (e.g ctrl + 1 so we can save the current selected troops and all we have to do to select those next time is to press the “1” key.
