Every other game that I've played in the past 25 years (going back, for me, to the original Diablo) has had an option to disable the ground targeting reticle step of casting AoE abilities and instead simply cast the ability at the cursor hover location when the button is pressed (League called it "smartcasting" and the term has stuck in my head since). Not having that option feels Real Bad after decades of using it across multiple game genres. Adding such an interface option would be simple to implement and would feel smooth and good to play (especially for oGCD ground effects - thinking of Earthly Star here) without taking away the indicator from those who want or need it.
