uhm I just tried it and I must say that she does feel more fluid... I don't say that as a good thing though since before she felt like a rock type champion, sturdy and a bit clumsy, she's now a lot more powerful and fast which is a good thing for the gameplay but not for the thematic of the champion itself, before it was as if she was starting to control her powers and like she was a bit afraid of them, now she's in full control.
Also, from a visual design standpoint her Vector cast W is problematic because you can't see the circle anymore, you can of course estimate it from playing a bit but still, it's just odd that you can't see the initial circle when you hover over the skill.
The fact that you can change your rotation is pretty cool though and if you ask me I'd vote to keep her old W cast type but getting rid of the lockout mechanic.
