Here's how I think about 5D change. 5D(1) had 7 active frames and was the responsible for scooping people who refused to tech in time. It's pretty much garanteed oki/punish if you Sweep>5D with no delay.
But now with less 7 frames, and abit of range nerf consequently, won't it give enough time for them to delay tech even after tight Sweep>5D?
I doubt ASW would overlook something like that, and it's still a loketest at the end of the day, but it's something to think about.
