skillshot indicators for the caster need adjustment around the board

One especially notable indicator that falls about 100 units short of the end of the ability is Blitzcrank's Q. But this happens with quite a few skillshots. Some don't actually reach the end of the arrow while others soar past it to hit their mark.

This needs to be fixed, especially since the default setting for new players was changed to quickcast with indicator. And since the arrow type indicator has been an issue ever since the game started, I'd suggest every ability have something more along the lines of Thresh's E, where it shows the rectangle that actually is the ability's hitbox and arrows inside it to show direction. This could just be a single arrow ->] at the cursor.

As a side note, there should also be clarification on every ability as to whether it needs to hit the center or the edge of a champion's hitbox.
