Kaiser d/cing issue

I've only noticed this issue with Blade Burst. Initially, I had Blade Burst on the direction+down+attack combo, and I always noticed my character crouching down as I dced, so I thought maybe it was the down+attack that was dcing me, which, I've heard is also an issue. However, I switched Blade Burst to direction+up+attack, and eventually I dced that way as well, as well as spamming Blade Burst using a key assignment.
