Better Targeted Attack System

After playing some top lane I noticed something very bs.

Why is it that using the spells like blind or ignite have to be pinpoint precise when attack click move is free to be a rough estimate?

I believe that any non-skillshot abilities that behave almost like a right click should be opted to function like an attack move click so you can be 1 or 2 pixels off and still pull it off. It will reduce rage and toxicity, and make a better gaming experience.
