quick castish thing

so as we all know everyone loves quickcast bit everyone also love indicators... so what if we had a quick cast with indicators.but instead of having to click to activate the spell you just have to release the button. as jax players know indicators are sick but know like having to left click their q to activate it. so u just hold your cursor over the target you want and just release q or release e but it still has indicators. this is especially great on thresh because you don’t have to move your mouse behind thresh to be able to pull instead you just slight pull it back and it pull. it sound bad in theory but think about how great it would be. how many times u could have gotten that kill but you could click in time. what if u just had to release the key
