Zed W+E Combo bugged, as well as W+Q still bugged in 5.8

When hitting W>E really fast, the W goes out but the E does not when the shadow materializes after its travel time. What happens instead is zed uses E while the shadow is traveling and once the shadow spawns it does not replicate the E. Using W>Q really fast the shadow's Q does the animation but the shuriken disappears almost instantaneously, and actually does no damage even if it does happen to hit anything while in its limited animation. Lastly, this has also been going around for a while, but it seems no longer possible to avoid damage of certain abilities while ulting. I know the animation was increased in 3.13 (I believe), but they never stated that Zed is now targettable during the beginning of this new animation. Would like some clarification on that if possible. These bugs are all easily replicated on any Zed skin, on any map, both with or without smartcast on. Recently there was a video made on youtube showcasing both the W>E and W>Q bugs. Credit to EONS Imiji for the video which I could not create. [(https://www.youtube.com/watch?v=5rudfXtsCMs)]
