A Very Minor Thresh Buff

Even though Thresh is the most popular support, he only has a win rate of 48.45%. He is very difficult to play, high CD, somewhat long cast time one his Q,W,R, However, the small buff I hope for has nothing to do with any of these since they are necessary for counterplay. The buff I wanted has something to do with the way his W is thrown. When you have quick-cast on, it is difficult to tell how big the area of the shield covers, making it hard to land if you are trying to shield someone out of range. I would like Thresh's lantern to be thrown so that the EDGE of the lantern lands on the cursor location when you cast it out of range (not really sure how to phrase this, but if you know what I'm talking about and have a better description for this please let me know).
