Bug about Zed after upgrading.

When using WEQ combo quickly,the Q skill Razor Shuriken cast by shadow of Zed is slow than previous beta extremely.In theory , shadows' Razor Shuriken should prior to cast ,whereas in this beta shadow's Razor Shuriken will cast until Zed himself 's Razor Shuriken reached its limited range.

I am sorry that my description may hard to understand since I am a Chinese student and English not good yet,but I am sure that it is real has a bug of Zed. Please check.
