Why no range circles for groups?
The inherent problem with range circles is how to best show them. We could show all of them but that would defeat the purpose of having the group view. We could only show the outer limit of the overlapping ones. This also has the effect of slowing down the game to the point where it would become unacceptable. Nevertheless, many people have requested this option and it may appear in a future version. We recommend you try using the group view and switching to the unit view (via the “9” hotkey) for ranges.
