as far as i understand it, the strength (or what ever) of ranged powers does not decrease when they hit several structures or units. so the positioning of the heros is crucial. it woul be nice if we could select (and also change during play) at least one of the equipped powers (including invos) such that their range and how many structures are in range is displayed before releasing them. i would find something like this very useful to find a good position and it would also be good for new players or for teaching others. what do you think?
edit: another possibility would be if some kind of markers (e.g. colored dots, small pictures …) appear at least on structures if they are in range of any of the equipped powers of the hero. or a combination of this two suggestions - draw a circle of the selceted power and change color (make a dot onto…) of structures in range. anything like this.
