This would definitely benefit the game by a lot i'll explain to you all what it is.
This is the AoE range Indicator that we all know in love it lets us know how far we can cast an ability.
The Effective AoE Indicator would look like this. It is the Area of Effect that effects enemies from the point of which the ability is used. Also I think that Stardock should have the Normal AoE range indicator present when using an ability as well, not just after putting your cursor over it.
(keep in mind this was done in paint I have no idea if that is the actual area of effect that Fracture effects)
