Take my timestamp and slow the video down, notice exactly when the melee swing begins:
Compare it to this timestamp:
The first video is not necessarily even at max leeway range and it’s still very close to the second video. People are really forgetting that that beta video is showing the MAXIMUM leeway range and that’s a lot harder to come across in actual PvP.
I even took a screenshot:

This alongside the confirmation from Blizzard that melee leeway is working as intended should settle this debate. It won’t though, because people can’t accept being wrong about anything.
