IMO the flag and supply rings are rather obtuse. They’re not ugly but they can become quite noisy, particularly on maps with lots of flag points and around main bases where half a dozen or more can show up.
I suggest making it so that these rings only show up when the unit creating them is selected, AND/OR mouseover; mouseover would be more intuitive/faster, rather than having to select the thing you just have to mouseover for a split second to see where you need to send your guys.
Mouseover should also work for checking the radius on enemy flags since you don’t have to select them (and can’t, as they’re enemies).
It’d just help remove some of the clutter while keeping it functional.
