Attack Move versus Right Click attack inputs

Something ive been seriously wondering about as an adc player. is it intentional to have a slower input to the game for attack move than right click attack? because ive noticed it causes some disruptions with animations (probably because it has to find the time to seek a target or something). are there any plans for the future to make this smoother, i would much like to see it happen even though it probably takes a lot of recoding
