It would be very handy for me if for example good status effects that need ground targeting would just default as being cast under your character, for example Sacred Soil. Then I could just press the macro and Enter and boom it would be where I am standing.

Then again abilities like Flaming Arrow, why can't it default under my current target? Just think this would be handy.

Otherwise you could keep controls the same, aka if you move your mouse after pressing the button then it starts targeting the ability like it does now.
