@RIOT, my feedback for 6.20 change to Yorick's W. Could I receive any context?

So, in 6.20 Patch we saw a change to Yorick's W: > W - Dark Procession DARK USABILITY Yorick will now cast at his maximum range if Dark Procession is cast outside of its maximum range

At first I though it was some quality of life buff, but it turned out be a massive quality of life nerf. Ever since his W has been absolutely terrible to use. I bought Yorick after his rework, now I am sitting on 23K mastery lvl 5. I played a lot of new Yorick and I find this change absolutely horrible. In previous patches I learned to land my W and trap the intended player most of the times, but ever since I am about to actually trap an enemy, unless they are at melee range, not trying to run away. Given how core this spell is for Yorick's game-play this change is a massive nerf on him. This can be just me being a terrible player, but as I said: I used to land the wall pretty often. So this is my feedback. Let me explain with a few examples:

{Me}: Yo, Yorick, our teammate is being chased in the jungle. Put the wall in this corridor to ensure his escape. : You mean to put it on the top of the wall? {Me}: ... Why would I mean this?

{Me} Yo, Yorick, an enemy is trying to push our turret. Put the wall behind him to cut his escape and help out team engage on him. : You mean to put it right between myself and him? {Me}: ... Why would I mean this?

{Me}: Yo, Yorick, the enemy is stunned. Put the wall around him to ensure the kill for your team. : You mean just next to him? {Me}: ... Why would I mean this?

{Me}: Yo Yorick, an enemy is TP-ing over here, put the wall around his TP location. : You mean just next to it? {Me}: ... Why would I mean this?

The list goes on, but I think I made myself clear. It is the worst when your target is just outside the W range, so instead of cutting their escape it does nothing.

**It feels that the character places the spell where he wants and he does not do what I told him to do, which is never a good thing. **

No area should work this way, IMO, and I actually checked:

Casting Cait's W makes her walk until she gets in range. Casting Zyra's W makes her walk until she gets in range. Casting Soraka's Q and E makes her walk until she gets in range. Casting Veigar's E makes him walk until he gets in range. Placing a ward with any champion makes them to walk until they are in range. If the player wants to place his glass on the table and it is outside his arms reach he walks toward the table. The list goes on.

So, I guess asking for a revert will have as much of an effect as it has with Taliyah's vector cast, but still: Can you revert that change? http://weknowmemes.com/generator/uploads/generated/g1352217865361546904.jpg

And if not - could you please explain why did you make this change?
