well 6a comboing was good in that you could use it as a reset in the corner for a risk...
like 6a as soon as they tech, 6a into 623 b for a free corner combo since people usually block low on wakeup, and the animation would be semi-hidden from their tech
and 6b shouldnt be an overhead, its way too good in that it moves jin up, and can be canceled into from any ground normal, as well as doing crazy meterless damage with 6b>6c
