Still don’t think people are understanding the point. Leeway existed in vanilla, that has been addressed, reviewed, and Blizz confirmed.
The issue is that Blizz is stating the current leeway mechanic is “working as intended” and it is not. If you want some better context on how it is not I’d reference the following video post at 7min mark:
I don’t think people should be debating the existence, but instead be considering that the leeway functionality both from a spell and melee perspective is not behaving correctly as it did in vanilla.
