lel I remember fighting her a not too long ago...punished several things and made her eat several grounded moves, simply because she was just rolling around...and she blamed every loss on lag...when there really wasn't any.
iirc her words were "that was laggy", "I might not be the best, but I know how to block, which I couldn't do because of lag" or something like that...
There is a risk in laser focused stab punishment in Soulcalibur V. You may get booted for king crab lag. (Since it's rather difficult to block at negative frames.)
