Any decent Kung Lao player would use this to close out a game and they would duck and wait for a split second (at least 2o frames... lol) to avoid any wakeup invincibility to wear off then Xray if she tried anything. The only thing she could do to get out would be 1. d+3 and risk being countered, 2. block if she has more than 2% life left or 3. jump back then Kung Lao can simply dash forward and Xray.
