This bug fix impacted the League of Legends(tm) community, myself included.

(copy and pasted from patch notes) W - Living Shadow
SHADOW MAGIC: Fixed a bug where casting Razor Shuriken before Living Shadow would allow the shuriken to be cast from the shadow

Zed Q > W trick (video displaying it) Sorry it is not in English, it is the best video I could find displaying the trick. The other videos were of poor quality and/or did not display the trick as well. (He shows it off many many times, slow motion replay included). You don't need the audio. Just watch it, and you will understand. 

So there was a 'bug' that when you threw your Razor Shuriken as Zed, then cast Living Shadows quickly, your shadow would also throw a Razor Shuriken. It worked in the same way the W > E works. It will activate as soon as your shadows spawns. I think it is neat that it works this way, it fit together nice. Q > W and/or  W >  E combos.

Many people I talked to really enjoyed it (me included) and did not like the bug fix. I have read many posts that players have made in the League of Legends(tm) forum, asking to bring it back. I would also be someone that wanted it back. 

Please undo this 'bug-fix' and implement it.
